Parameter name prefix
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
When choosing a ParameterType.NAMED to produce named parameters, the default is to use a colon as a prefix to the parameter name.
For example:
-- NAMED SELECT FIRST_NAME || :1 FROM AUTHOR WHERE ID = :x
Depending on how the named parameters are interpreted, this default is not optimal. A better character might be the $ sign, e.g. in PostgreSQL or R2DBC. For this, the renderNamedParamPrefix setting can be used:
Example configuration
Settings settings = new Settings()
.withRenderNamedParamPrefix("$"); // Defaults to ":"
