                    throws SQLException

Throws:

SQLException

Method Detail

isDuplicateKeyViolationMessage

public boolean isDuplicateKeyViolationMessage(String message)

Specified by:

isDuplicateKeyViolationMessage in class GeometryJdbcConverter

isFKConstraintViolationMessage

public boolean isFKConstraintViolationMessage(String message)

Description copied from class: GeometryJdbcConverter

bepaal of een melding een constraint violation betreft.

Specified by:

Throws:

SQLException

convertToNativeGeometryObject

public Object convertToNativeGeometryObject(org.locationtech.jts.geom.Geometry g)
                                     throws SQLException,
                                            org.locationtech.jts.io.ParseException

Specified by:

convertToNativeGeometryObject in class GeometryJdbcConverter

Throws:

SQLException

org.locationtech.jts.io.ParseException

getSchema

public String getSchema()

Specified by:

getSchema in class GeometryJdbcConverter

Returns:

the schema

setSchema

public void setSchema(String schema)

Parameters:

schema - the schema to set

getGeomTypeName

public String getGeomTypeName()

Specified by:

getGeomTypeName in class GeometryJdbcConverter

buildPaginationSql

public String buildPaginationSql(String sql,
                                 int offset,
                                 int limit)

Specified by:

buildPaginationSql in class GeometryJdbcConverter

buildLimitSql

public StringBuilder buildLimitSql(StringBuilder sql,
                                   int limit)

Voegt een limiet toe aan een query te gebruiken in geval van insert met select. Bijvoorbeeld zoals het plaatsen van stand-berichten in de job tabel. NB buildPaginationSql(java.lang.String, int, int) is niet bruikbaar voor een insert+select

Specified by:

buildLimitSql in class GeometryJdbcConverter

Parameters:

sql - query zonder limiet

limit - max aantal op te halen records dat voldoet aan query

Returns:

query met limiet

Since:

1.4.1

useSavepoints

public boolean useSavepoints()

Specified by:

useSavepoints in class GeometryJdbcConverter

isPmdKnownBroken

public boolean isPmdKnownBroken()

Specified by:

isPmdKnownBroken in class GeometryJdbcConverter

getGeotoolsDBTypeName

public String getGeotoolsDBTypeName()

Specified by:

getGeotoolsDBTypeName in class GeometryJdbcConverter

getMViewsSQL

public String getMViewsSQL()

Specified by:

getMViewsSQL in class GeometryJdbcConverter

getMViewRefreshSQL

public String getMViewRefreshSQL(String mview)

Specified by:

getMViewRefreshSQL in class GeometryJdbcConverter

getSelectNextValueFromSequenceSQL

public String getSelectNextValueFromSequenceSQL(String seqName)

Description copied from class: GeometryJdbcConverter

get the database flavour specific SQL statement to get the next value from a sequence.

Specified by:

getSelectNextValueFromSequenceSQL in class GeometryJdbcConverter

Parameters:

seqName - name of sequence

Returns:

SQL statement specific for the flavour of database

convertToJTSGeometryObject

public org.locationtech.jts.geom.Geometry convertToJTSGeometryObject(Object nativeObj)

de geotools converter is niet round-trip safe, er treed een NPE op als een 'lege' geometrie wordt aangeboden:

    at org.geotools.data.oracle.sdo.SDO.ETYPE(SDO.java:1681)
    at org.geotools.data.oracle.sdo.SDO.create(SDO.java:1933)
          at org.geotools.data.oracle.sdo.GeometryConverter.asGeometry(GeometryConverter.java:121)
 

dat is een bug in geotools.

Specified by:

convertToJTSGeometryObject in class GeometryJdbcConverter

Parameters:

nativeObj - uit de database

Returns:

jts geom of null

getUpdateSequenceSQL

public String getUpdateSequenceSQL(String seqName,
                                   long nextVal)

Gets a statement to use in a prepared statement to restart a sequence. This assumes no other interactions are going on with the sequence; can only be used to increase the value of the sequence, not decrease.

Overrides:

getUpdateSequenceSQL in class GeometryJdbcConverter

Parameters:

seqName - name of sequence

nextVal - the value to restart the sequence, some systems require this to be larger than the next value of the sequence.

Returns:

SQL statement specific for the flavour of database
