The following query shows INSTR() considering characters, and SUBSTR() working on bytes. (The query is attempting to strip the extra '"' at the end, but end up cutting too much in the presence of multi-bytes characters. This makes using SUBSTR() on boundaries computed ...

Yes, the INSTR function can search backwards in a string if the position parameter is negative. This means it starts counting from the end of the string and searches backward from that position. 5.What does the Oracle INSTR function return? The INSTR function returns an integer representing the...
My idea was to select the string after the equal "1234sg654", in this way: with Instr() find position of equal, after that with Substr(), subtract the string after equal until end of string. equal=INSTR(string,'=',1,1); aux=Substr(string,-1,equal); // -1 I thought that is ...

This string can not be passed directly to the parser as it is most likely not a valid SQL-statement. Note as it can be seen in the get_query() implementation, get_expr_query() might return EMPTY_CSTR. EMPTY_CSTR means that no query-expression is available. That happens when class ...
In this basic example, we are searching for a pattern in a string and the search is case-insensitive. We have specified the return_option parameter as 0 which means the position of the first character of the pattern will be returned. Now, let's change the return_option parameter to 1 an...

The "^" in the brackets represents NOT and "+" means 1 or more. We also want to remove optional double quotes, so we add that as a character we don't want, giving us "[^/"]+". So if we want the data from the third column, we need the third occurrence of this pattern....
SQL INSTR: The Basics INSTR searches for a substring within a string and returns its starting location in the string, using the syntax INSTR(string,substring). This means that if you tell INSTR to look for “berry” in “strawberry” it will return 6, because “berry” starts at position...
