BUT I CAN'T INSERT. BECAUSE ERROR "DATA MISS MATCH" PLEASE HELP ME.

Answer 1

I agree with Frank on the issue with dates... It could also be trying to do a text into a numeric field (or any other such swapping).
However, a bigger issue might be if/when you get into using a true SQL database such as Oracle, SQL-Server, MySQL, etc... (not that I have anything against VFP and have been programming with Foxpro since '85) But doing SQL statements like you have, especially in any web-based system would leave you wide-open to SQL-injection attacks.
Its better to use parameterized query/insert/update/deletes.

Answer 2

A Data Type Mismatch error occurs when you try to insert an inappropriate data type into a field. For example, if you try to store a string into an integer field.
At first glance I think the format of your dates is the problem. Change "'1987/10/10'," to "{^1987-10-10},".
If changing the dates does not correct the problem, it would be helpful if you could show me the result of the strSQL variable and structure of the ag_mas table.

Answer 3

I agree with Frank in regards to a solution and I believe that DRapp has a valid point about how you are going about your insert statement. To add to DRapp’s suggestion, I’d like to point out that you could use LINQ to VFP to handle writing all your sql commands.
