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. The LENGTH () function can give the length of the search string. Those two values together essentially tell where the colon will be.

iDB2-FAQ-003: String manipulation with SQL (POSSTR, LOCATE, LOCATE_IN_STRING) Remaining in the theme of string manipulation with SQL we wrote a special article for the functions POSSTR (position inside a string), LOCATE and LOCATE_IN_STRING, always for positioning inside the strings but with a slightly Different:

However, POSSTR() can be used and it can locate the position of a search-string within a string. The LENGTH() function can give the length of the search string.

Replace the DB2 POSSTR function with INSTR SELECT INSTR(string, substring, position, occurrence) DATE FUNCTIONS / DATE MATH. In DB2, you could use the DATE() function to get the date portion of a datetime field.

Something like that: INSERT INTO TABLE1 (ID, COLUMN1) VALUES (SELECT ID, CLOBCOLUM????

NOTE. DB2 V6 significantly improved IBM's support for built-in scalar functions. Prior to DB2 V6 there were only 22 built-in scalar functions. Additional built-in functions were added for DB2 V7 and V8, as well.

Additional built-in functions were added for DB2 V7 and V8, as well. POSSTR. Similar to the LOCATE function, but with the arguments reversed. 2021-03-19 How to clean up DB2 string from unreadable characters ?

Often, in our applications, we need to work with text strings, and DB2 SQL can come in very useful and simplify our code.
