                                    throws SQLException
```
    Description copied from class: SQLDialect
    
    Turns the specified srid into a CoordinateReferenceSystem, or returns null if not possible.
    Note this implementation takes account of SQLDialect.forceLongitudeFirst which should be set when longitude first (XY) axis ordering is required.
    The implementation might just use CRS.decode("EPSG:" + srid), but most spatial databases will have their own SRS database that can be queried as well.
    As a rule of thumb you should override this method if your spatial database uses codes that are not part of the EPSG standard database, of if for some reason you deem it preferable to use your database definition instead of an official EPSG one.
    Most overrides will try out to decode the official EPSG code first, and fall back on the custom database definition otherwise

```
    Description copied from class: SQLDialect
    Encodes the name of a geometry column in a SELECT statement.
    This method should wrap the column name in any functions that are used to retrieve its value. For instance, often it is necessary to use the function asText, or asWKB when fetching a geometry.
    This method must also be sure to properly encode the name of the column with the SQLDialect.encodeColumnName(String, String, StringBuffer) function.
    Example:
```
   
   sql.append( "asText(" );
   column( gatt.getLocalName(), sql );
   sql.append( ")" );

```
    Description copied from class: SQLDialect
    
    Decodes the result of a spatial extent function in a SELECT statement.
    This method is given direct access to a result set. The column parameter is the index into the result set which contains the spatial extent value. The query for this value is build with the SQLDialect.encodeGeometryEnvelope(String, String, StringBuffer) method.
    This method must not read any other objects from the result set other then the one referenced by column.
    
    Specified by:
    
    decodeGeometryEnvelope in class SQLDialect
    
    Parameters:
    
    rs - A result set
    
    column - Index into the result set which points at the spatial extent value.

                         throws IOException
```
    Description copied from class: BasicSQLDialect
    Encodes a geometry value in an sql statement.
    An implementations should serialize value into some exchange format which will then be transported to the underlying database. For example, consider an implementation which converts a geometry into its well known text representation:
```
   
   sql.append( "GeomFromText('" );
   sql.append( new WKTWriter().write( value ) );
   sql.append( ")" );
   
  
```
    The srid parameter is the spatial reference system identifier of the geometry, or 0 if not known.
    Attention should be paid to emtpy geometries (g.isEmtpy() == true) as they cannot be encoded in WKB and several databases fail to handle them property. Common treatment is to equate them to NULL

```
    Description copied from class: SQLDialect
    Decodes a geometry value from the result of a query.
    This method is given direct access to a result set. The column parameter is the index into the result set which contains the geometric value.
    An implementation should deserialize the value provided by the result set into Geometry object. For example, consider an implementation which deserializes from well known text:
```
   String wkt = rs.getString( column );
   if ( wkt == null ) {
     return null;
   }
   return new WKTReader(factory).read( wkt );
   
```
    Note that implementations must handle null values.
    The factory parameter should be used to instantiate any geometry objects.

  - lookupGeneratedValuesPostInsert
```
public boolean lookupGeneratedValuesPostInsert()
```
    Description copied from class: SQLDialect
    Controls whether keys are looked up post or pre insert.
    When a row is inserted into a table, and a key is automatically generated it can be looked up before the insert occurs, or after the insert has been made. Returning false will cause the lookup to occur before the insert via SQLDialect.getNextAutoGeneratedValue(String, String, String, Connection). Returning true will cause the lookup to occur after the insert via SQLDialect.getLastAutoGeneratedValue(String, String, String, Connection).
    Subclasses returning false should implement:
    - SQLDialect.getNextAutoGeneratedValue(String, String, String, Connection)
    Subclasses returning true should implement:
    - SQLDialect.getLastAutoGeneratedValue(String, String, String, Connection)
    Overrides:

    isLimitOffsetSupported in class SQLDialect
  - applyLimitOffset
```
public void applyLimitOffset(StringBuffer sql,

                             int offset)
```
    Description copied from class: SQLDialect
    
    Alters the query provided so that limit and offset are natively dealt with. This might mean simply appending some extra directive to the query, or wrapping it into a bigger one.

                     throws SQLException
```
    Description copied from class: SQLDialect
    
    Determines if the specified table should be included in those published by the datastore.
    This method returns true if the table should be published as a feature type, otherwise it returns false. Subclasses should override this method, this default implementation returns true.
    A database connection is provided to the dialect but it should not be closed. However any statements objects or result sets that are instantiated from it must be closed.
    Overrides: includeTable in class SQLDialect Parameters: schemaName - The schema of the table, might be null.. tableName - The name of the table. cx - Database connection. Throws: SQLException

Mind, it may be retyped and thus contain less geometry columns than the table Returns: a list of referenced envelopes (some of which may be null or empty) Throws: SQLException IOException isUseSelectivity public boolean isUseSelectivity() setUseSelectivity public void setUseSelectivity(boolean useSelectivity) supportsSchemaForIndex protected boolean supportsSchemaForIndex() Description copied from class: SQLDialect Return true if the database supports individual schemas for indices. The SQL encoding would be CREATE INDEX SCHEMANAME.INDEXNAME ON .... The default is false and the encoding is CREATE INDEX INDEXNAME ON .... Overrides: supportsSchemaForIndex in class SQLDialect Returns: true or false canGroupOnGeometry public boolean canGroupOnGeometry() Description copied from class: SQLDialect Returns true if this database can "group by" on a Geometry column. Defaults to false, specific implementations with this capability should override Overrides: canGroupOnGeometry in class SQLDialect
