Database.Beam.Backend.SQL.Builder
Description
Provides a syntax SqlSyntaxBuilder that uses a
Builder to construct SQL expressions as strings.
Mainly serves as documentation for how to write a syntax for backends. Note
that, although you can use this to turn most Q and QGenExprs into
ByteString queries, it is very unwise to ship these to the database.
This module does not take into account server-specific quoting. Some
backends are very particular to quoting, and shipping arbitrary
ByteStrings as queries can expose you to SQL injection vulnerabilities.
Always use the provided backends to submit queries and data manipulation
commands to the database.
