sqlldr error in Oracle - oracle

Question

Currently, I am using sqlldr userid= {user}/{pass}#{SID} to load the file into database, and this comment is in a bash file.
The password is generated by a third lib framework.
But, I found that sometimes I got the following error,
export TNS_ADMIN=/opt/config/uat/
export PATH=$PATH:$ORACLE_HOME/bin
sqlldr userid=M_UAT/YAu8D=5r#My_UAT
ERR>LRM-00116: syntax error at 'M_UAT/YAu8D' following '='
I found that there is a special character = in the password,
I checked something, seems sqlplus can avoid this exception by userid= ={user}/\"{pass}\"#{SID}
But sqlldr cannot.
Does anyone have an idea here?

Answer 1

sqlplus makes a connection with the username and password in quotes. The sqlloader(sqlldr) connects to the database only if the name is written without quotes.
The password can contain #!= characters only in quotation marks, for example
password=\"YAu8D=5r\"
password=\"#!YAu8D=5r#\"
Example 1
username=HR
password=\"YAu8D=5r\"
Change password
