Method Detail

renderWhereStringTemplate

public static String renderWhereStringTemplate(String sqlWhereString,
                                               Dialect dialect,
                                               SQLFunctionRegistry functionRegistry)

renderWhereStringTemplate

public static String renderWhereStringTemplate(String sqlWhereString,
                                               String placeholder,
                                               Dialect dialect)

Deprecated. Only intended for annotations usage; use renderWhereStringTemplate(String, String, Dialect, SQLFunctionRegistry) instead

Same functionality as renderWhereStringTemplate(String, String, Dialect, SQLFunctionRegistry), except that a SQLFunctionRegistry is not provided (i.e., only the dialect-defined functions are considered). This is only intended for use by the annotations project until the many-to-many/map-key-from-target-table feature is pulled into core.

public static String renderWhereStringTemplate(String sqlWhereString,
                                               String placeholder,
                                               Dialect dialect,
                                               SQLFunctionRegistry functionRegistry)

Parameters:

sqlWhereString - The string into which to interpolate the placeholder value
