in reply to Interpolating subroutine call in SQL INSERT INTO SELECT statement

I agree with Anonymous Monk that there is nothing wrong with using two SQL statements in this situation. But what is the function of the subroutine to which you want to pass the value of COLUMN3 ? Could you use an existing SQL function in your SELECT query? Or could you build a stored routine for your DB?

Built-in SQL functions
Stored routines in MySQL


The way forward always starts with a minimal test.

    It did not even cross my mind to attempt either using an existing SQL function or building a stored routine within my DB and using that.

    I have written a Perl function that takes a string and substitutes out certain characters from that string (the characters I'm taking out belong to a hash that I can extend as and when I need to

    I'm not sure whether I can use an existing SQL function to achieve this, but it seemed like a good idea to have that function coded in Perl - seeing as how great Perl is with RegExps and the other programmer likely to be maintaining the code knows Perl..

    Thanks for the advice! Once I get a handle on creating stored procedures in MSSQL I'm sure I'll be looking for every excuse to use them.
