I have a complex query that creates a master CTE_Table form other CTE_Tables. I want to insert the results of the master CTE_Table into a physical table. I'm using Teradata version 15.10.04.03
SELECT Failed. [3707] Syntax error, expected something like a 'SELECT' keyword or '(' or a 'TRANSACTIONTIME' keyword or a 'VALIDTIME' keyword between ')' and the 'INSERT' keyword.

While you are missing the INSERT portion of the question, I think the following might clear things up. The correct format for using a CTE in an INSERT is:
INSERT INTO <tablename>
WITH <cte> AS (SELECT...)
SELECT <fields> FROM <cte>
Consider the following:
CREATE MULTISET VOLATILE TABLE tmp AS (SELECT 'bobby' as firstname) WITH DATA ON COMMIT PRESERVE ROWS;
INSERT INTO tmp
WITH cte AS (select 'carol' as firstname)
SELECT * FROM cte;
SELECT * FROM tmp;
DROP TABLE tmp;

I have load data infile .... one flat file. I want to load the data into table tab from this flat file. I want to pass few values like 'ab', 'cd', 'ef' in column col6 of the table. When i write the code in the flat file like this
load data infile <source-path>
into tab
fields terminated by ','
(
col1 "TRIM(:col1)" ,
............
...........
col6 "('ab','cd','ef')",
..........)
But when i load this file into the table then i found an error ORA-00907: Missing Right Parenthesis. How to resolve this error so that i can insert value of 'ab', 'cd', 'ef' in col6 of table tab.
You can use a multitable insert, with three inserts into the same table:
load data infile <source-path>
into tab
fields terminated by ','
(
col1 "TRIM(:col1)" ,
............
...........
col6 CONSTANT 'ab',
..........)
into tab
fields terminated by ','
(
col1 POSITION(1) "TRIM(:col1)" ,
............
...........
col6 CONSTANT 'cd',
..........)
into tab
fields terminated by ','
(
col1 POSITION(1) "TRIM(:col1)" ,
............
...........
col6 CONSTANT 'ef',
..........)
The POSITION(1) resets to the start of the record, so it sees the same values from the source record again fir each insert. Read more.
Alternatively you could insert into a staging table, with a single row for each record in your file, and excluding the constant-value col6 completely - which you could with SQL*Loader:
load data infile <source-path>
into staging_tab
fields terminated by ','
(
col1 "TRIM(:col1)" ,
............
...........
col5 ...
col7 ...
..........)
... or as an external table; and then insert into your real table by querying the staging table and cross-joining with a CTE containing the constant values:
insert into tab (col1, col2, ..., col6, ...)
with constants (col6) as (
select 'ab' from dual
union all select 'cd' from dual
union all select 'ef' from dual
)
select st.col1, st.col2, ..., c.col6, ...
from staging_tab st
cross join constants c;
For each row in the staging table you'll get three rows in the real table, one for each of the dummy rows in the CTE. You could do the same with with a collection instead of a CTE:
insert into tab (col1, col2, col6)
select st.col1, st.col2, c.column_value
from staging_tab st
cross join table(sys.odcivarchar2list('ab', 'cd', 'ef')) c;
This time you get one row for each element in the collection - which is expanded into multiple rows by the table collection clause. The result is the same.
I have 2 different tables and I want to delete records from table1 which does not exist in Tables2
Table1:
select col1 from Table1
Table2:
select
concat('A_',col1)
from
Table2
where
Col2 = '748'
and Col3 = 'D'
and Col4 = 'Account'
now I want to delete the difference from Table1...
This can be done using the minus operation, and an insert into statement.
insert into table3(col) (
select col1 from Table1
minus
select
concat('A_',col1)
from
Table2
where
Col2 = '748'
and Col3 = 'D'
and Col4 = 'Account'
)
Records can then be deleted from table1 using a delete statement like
delete from table1
where col1 in (
select col1 from Table1
minus
select
concat('A_',col1)
from
Table2
where
Col2 = '748'
and Col3 = 'D'
and Col4 = 'Account'
)
delete from table1 t1
where not exists ( select * from table2 where col2 || col3 || col4 = t1.col1 );
This will work EXCEPT for the following situation; you need to explain what you want in that case. The DELETE statement can be modified to accommodate.
If t1.col1 is NULL, it will be deleted even if there are rows in table2 where col2, col3 and col4 are all NULL. Is that situation possible (where t1.col1 and col2, col3, col4 in table2 are all NULL? In that case, should the row in t1 be kept rather than deleted?
Have 2 tables with same columns and want to generate the difference between the tables and want to show the difference listing all columns from both tables
example:
select a.*,b.* from (
(
select a.col1,a.col2 from
(select col1, col2 from table1 minus select col1, col2 from table2) as a
)
union
(
select b.col1, b.col2 from
(select col1, col2 from table2 minus select col1, col2 from table2) as b
)
)
The result should be
a.col1 a.col2 b.col1 b.col2
a.FName a.ZipCode b.FName b.ZipCode
John <same value> Jane <same value as A>
Alpha 1234 Beta 2345
My query returns exception that it is missing R parenthesis after the 1st minus keyword
I think you are trying to find rows from table a which are missing in table b and rows in table b which are missing from table a. However, there is no point in joining these two sets. Try the following query and see if it works for you.
SELECT col1, col2, 'Missing from table 2' title
FROM
(
SELECT col1,
col2
FROM table1
MINUS
SELECT col1,
col2
FROM table2
)
UNION ALL
SELECT col1, col2, 'Missing from table 1' title
FROM
(
SELECT col1,
col2
FROM table2
MINUS
SELECT col1,
col2
FROM table1
)
I just recently found out that subqueries are not allowed in INSERT statements that are inside stored procedures. This is my script:
begin
execute immediate 'truncate table itcustadm.GL_DTPJ_TEST2';
insert into GL_DTPJ_TEST2
(rule_no,
posted_by_user_id,
transaction_id,
transaction_sr_no,
dr_amount,
cr_amount,
tran_crncy_code,
bkdt_tran_flg,
bank_desc
)
select
tq.rule_no,
tq.posted_by_user_id,
tq.transaction_id,
tq.transaction_sr_no,
tq.dr_amount,
tq.cr_amount,
tq.tran_crncy_code,
tq.bkdt_tran_flg,
(select ent.bank_desc from crmuser.end ent where ent.bank_id = gam.bank_id);
But since the (select ent.bank_desc from crmuser.end ent where ent.bank_id = gam.bank_id) at the bottom of the SELECT statement is not allowed by Oracle, what's the best way to accomplish this?
I actually have this code right before the INSERT statement, but I don't know how to exactly use it:
get_bank_desc := '(select ent.bank_desc from crmuser.end ent ' ||
'where ent.bank_id = gam.bank_id)';
I am not sure what you are exactly trying for, but below code may be useful for you, you can achieve inserting a SubQuery output into a table using below query sample, but make sure output of the SubQuery is a single row o/p, so that you can escape from "ORA-01427: single-row SubQuery returns more than one row" ERROR.
insert into test_ins1
values(1,(SELECT COL2 FROM TEST_INS WHERE COL1=1 ));
Even then you can use rownum in where condition and take the single value.
Please let me know in case of any doubts
declare
bank_desc_temp bank_desk_type; /* the type defined in crmuser.ent for bank_desc*/
begin
select ent.bank_desc into bank_desc_temp from crmuser.end ent where ent.bank_id = gam.bank_id;
execute immediate 'truncate table itcustadm.GL_DTPJ_TEST2';
insert into GL_DTPJ_TEST2
(rule_no,
posted_by_user_id,
transaction_id,
transaction_sr_no,
dr_amount,
cr_amount,
tran_crncy_code,
bkdt_tran_flg,
bank_desc
)
select
tq.rule_no,
tq.posted_by_user_id,
tq.transaction_id,
tq.transaction_sr_no,
tq.dr_amount,
tq.cr_amount,
tq.tran_crncy_code,
tq.bkdt_tran_flg,
bank_desc_temp;
end;
When you say "not allowed" what do you mean? Did you get an error?
I ask, because subqueries are definitely allowed inside an insert as select statement, providing you have the syntax correct (and the subquery returns at most one row), e.g.:
create table test_tab (col1 number, col2 varchar2(10));
begin
insert into test_tab
select 1,
(select 'Yes' from dual d2 where d.dummy = d2.dummy)
from dual d;
commit;
end;
/
select * from test_tab;
COL1 COL2
---------- ----------
1 Yes
There are some syntax issues with the code you provided - where is the from clause, and where are the tq and gam aliases defined?
There are two syntax you can use in your insert statement:
(I)
INSERT INTO table_name( column1, column2....columnN)
VALUES ( value1, value2....valueN);
(II)
INSERT INTO table (column1, column2, ... )
SELECT expression1, expression2, ...
FROM source_table(s)
WHERE conditions;
In your example, you should choose the second approach:
insert into GL_DTPJ_TEST2 (rule_no,
posted_by_user_id,
transaction_id,
transaction_sr_no,
dr_amount,
cr_amount,
tran_crncy_code,
bkdt_tran_flg,
bank_desc
)
select tq.rule_no,
tq.posted_by_user_id,
tq.transaction_id,
tq.transaction_sr_no,
tq.dr_amount,
tq.cr_amount,
tq.tran_crncy_code,
tq.bkdt_tran_flg,
ent.bank_desc
from crmuser.gam
join crmuser.end ent
on ent.bank_id = gam.bank_id
;
basically, if you want to add records using an insert statement, you should use a full select statement first. Here is how I would do it:
(1)
select *
from table1;
(2)
select column1
,column2
,column3
from table1;
(3)
select t1.column1
,t1.column2
,t1.column3
,t2.column4
,t2.column5
from table1 t1
join table2 t2
on t2.id = t1.id
;
(4)
insert into table3 (col1
,col2
,col3
,col4
,col5)
select t1.column1
,t1.column2
,t1.column3
,t2.column4
,t2.column5
from table1 t1
join table2 t2
on t2.id = t1.id
;
update tablename set (col1,col2,col3) = (select col1,col2,col3 from tableName2 order by tablenmae2.col4) return error
Missing ). The query works fine if I remove the order by clause
ORDER BY is not allowed in a subquery within an UPDATE. So you get the error "Missing )" because the parser expects the subquery to end at the point that you have ORDER BY.
What is the ORDER BY intended to do?
What you probably have in mind is something like:
UPDATE TableName
SET (Col1, Col2, Col3) = (SELECT T2.Col1, T2.Col2, T2.Col3
FROM TableName2 AS T2
WHERE TableName.Col4 = T2.Col4
)
WHERE EXISTS(SELECT * FROM TableName2 AS T2 WHERE TableName.Col4 = T2.Col4);
This clumsy looking operation:
Grabs rows from TableName2 that match TableName on the value in Col4 and updates TableName with the values from the corresponding columns.
Ensures that only rows in TableName with a corresponding row in TableName2 are altered; if you drop the WHERE clause from the UPDATE, you replace the values in Col1, Col2, and Col3 with nulls if there are rows in TableName without a matching entry in TableName2.
Some DBMS also support an update-join notation to reduce the ghastliness of this notation.
