Db2 SUBSTRING () function overview The SUBSTRING () function allows you to extract a substring from a string. The basic syntax of the SUBSTRING () function is the following: SUBSTRING (source_string, start_position [, substring_length ]); Often, in our applications, we need to work with text strings, and DB2 SQL can come in very useful and simplify our code. In this guide we see some interesting SQL functions for string manipulation: POSSTR – Search for position within a string LOCATE and LOCATE_IN_STRING – Find the location with a few more options You can use the posstr function to locate a character in a string, and then use the substr function to retrieve a part from a string. This could be done from an anonymous block or stored procedure. You put this in a function (UDF): POSSTR – DB2 Function Similar to the LOCATE function, but with the arguments reversed.POSSTR returns the position of the first occurrence of the second argument within the first argument. Since INSTR () isn't available, it can't be used with DB2 on i. However, POSSTR () can be used and it can locate the position of a search-string within a string.
