Method Details

getCountSql

public String getCountSql(org.apache.ibatis.mapping.MappedStatement ms,
 org.apache.ibatis.mapping.BoundSql boundSql,
 Object parameterObject,
 org.apache.ibatis.session.RowBounds rowBounds,
 org.apache.ibatis.cache.CacheKey countKey)

Generates the SQL for the count query using an intelligent SQL parser.

Specified by:

getCountSql in interface Dialect

Parameters:

ms - the MappedStatement object

boundSql - the BoundSql object containing the original SQL and parameters

parameterObject - the parameter object for the query

rowBounds - the RowBounds object containing pagination parameters

countKey - the CacheKey for the count query

Returns:

the generated count SQL string

setProperties

public void setProperties(Properties properties)

Sets the properties for the dialect, initializing the CountSqlParser and OrderBySqlParser. Custom implementations of these parsers can be specified via properties.

Specified by:

setProperties in interface Dialect

Parameters:

properties - the properties to set, typically from the plugin configuration
