Alternative Approaches for Regular Expression Validation in SQL Server: Using LIKE Pattern Matching to Detect Invalid Data
This article explores the challenges of implementing regular expression validation in SQL Server, particularly when checking existing database data against specific patterns. Since SQL Server does not natively support the REGEXP operator, we propose an alternative method using the LIKE clause combined with negated character set matching.
