CHARINDEX in SQL Server - Examples & AI Generator
Understanding CHARINDEX in SQL Server can be a challenge, especially with syntax variations across databases and edge cases like case sensitivity or optional parameters. CHARINDEX helps you find the starting position of a substring in a string, but memorizing the syntax slows you down—especially when working across multiple SQL dialects. AI2sql streamlines this process by instantly generating accurate CHARINDEX queries with no coding required, saving time and reducing errors.

FAQ: CHARINDEX in SQL Server
What does CHARINDEX return if the substring isn't found?
It returns 0 if the substring does not exist in the searched string.
Is CHARINDEX case-sensitive in SQL Server?
Case sensitivity depends on the collation of the column or database. By default, most SQL Server collations are case-insensitive.
Can you find multiple occurrences with CHARINDEX?
CHARINDEX only returns the position of the first occurrence. Use additional logic (such as loops or nested queries) for further occurrences.
