How to parse an array with multiple space characters (define delimeter)?

Asked by jrram in Shell Scripting

Tags: ,

Good afternoon all,

I'm hoping someone could help me fix an issue I'm having with my code.  In the code below, I am trying to parse an file and run a series of SQL statements.  

To do this, I use a grep statement to get the list of all the "setup_sql" lines in the file.  I store these in an array.  Then, I try to use a for loop to read each line and run the statement against my database.  The problem is I think by default the "space" characters is used as the delimiter in the loop so the complete statement is being executed.

On the first pass, instead of "UPDATE AP_VENDOR SET PAYMENT_TERMS = 'CHK' WHERE STATUS = 'ACTIVE'" being executed, "UPDATE" is.

It executes like this.
query 1: UPDATE
query 2: AP_VENDOR
query 3: SET
...

How should I modify my code so that I can capture the entire line.  In the below scenario only two SQL statements should be executed.Start Free Trial
