Question

I have strings like:

var = This a string, [This is another string]

I would like to have them broken into something like this in PLSQL

var1 = This is string
var2 = This is another string

The comma should not be included if it is like:

, [

Basically this decides if there is another string.

How can I do it?

Thanks in advance 🙂

You could use a combination of SUBSTR and INSTR to split the string. For example, to obtain the first string, you can use something along these lines:

SELECT NVL(SUBSTR(var, 1, INSTR(var, ',') - 1), var)
FROM dual;

That is, find the index of the separator (INSTR(var, ',')), and then use SUBSTR to capture everything up to that index. Same applies to the second string.
