public static ParsedSql parseSqlStatement(String sql)
sql - the SQL statement
public static String substituteNamedParameters(ParsedSql parsedSql,
SqlParameterSource paramSource)
The parameter values passed in are used to determine the number of placeholder to be used for a select list. Select lists should be limited to 100 or fewer elements. A larger number of elements is not guaramteed to be supported by the database and is strictly vendor-dependent.
parsedSql - the parsed represenation of the SQL statementparamSource - the source for named parameters
parseSqlStatement(java.lang.String)
public static Object[] buildValueArray(ParsedSql parsedSql,
SqlParameterSource paramSource,
List<SqlParameter> declaredParams)

(may be null). If specified, the parameter metadata will
be built into the value array in the form of SqlParameterValue objects.
