CHARINDEX in Oracle - Examples & AI Generator
Finding the position of a substring in Oracle SQL can be challenging, especially since there’s no direct CHARINDEX function like in SQL Server. Instead, Oracle uses INSTR
, which differs slightly in parameter order and behavior. For SQL developers, analysts, and engineers working across databases, remembering these differences is time-consuming. AI2sql provides instant, production-ready Oracle CHARINDEX equivalents—no manual coding, no memorizing syntax.
CHARINDEX Syntax in Oracle
Oracle Alternative: INSTR()
Oracle does not have a direct CHARINDEX
function. Use INSTR
instead:
string: The text to search in.
substring: The text to find.
start_position (optional): Where to start searching (default: 1).
nth_appearance (optional): Occurrence number to find (default: 1).
KEY DIFFERENCE: Oracle’s INSTR
switches parameter order compared to SQL Server’s CHARINDEX
.
