Constructor Details

RDMSOS2200Dialect

public RDMSOS2200Dialect()

Method Details

createCaseFragment

public CaseFragment createCaseFragment()
Overrides:
createCaseFragment in interface Dialect

forUpdateOfColumns

public boolean forUpdateOfColumns()
The RDMS DB supports the 'FOR UPDATE OF' clause. However, the RDMS-JDBC driver does not support this feature, so a false is return. The base dialect also returns a false, but we will leave this over-ride in to make sure it stays false.
Overrides:
forUpdateOfColumns in interface Dialect

getAddColumnString

public String getAddColumnString()
Overrides:
getAddColumnString in interface Dialect

getCascadeConstraintsString

public String getCascadeConstraintsString()
Overrides:
getCascadeConstraintsString in interface Dialect

getCreateSequenceString

public String getCreateSequenceString(String sequenceName)
Overrides:
getCreateSequenceString in interface Dialect

getDropSequenceString

public String getDropSequenceString(String sequenceName)
Overrides:
getDropSequenceString in interface Dialect

getForUpdateString

public String getForUpdateString()
Since the RDMS-JDBC driver does not support for updates, this string is set to an empty string. Whenever, the driver does support this feature, the returned string should be " FOR UPDATE OF". Note that RDMS does not support the string 'FOR UPDATE' string.
Overrides:
getForUpdateString in interface Dialect

getLimitString

public String getLimitString(String sql,
                             int offset,
                             int limit)
Overrides:
getLimitString in interface Dialect

getLockingStrategy

public LockingStrategy getLockingStrategy(Lockable lockable,
                                          LockMode lockMode)
Overrides:
getLockingStrategy in interface Dialect

getNullColumnString

public String getNullColumnString()
Overrides:
getNullColumnString in interface Dialect

getSequenceNextValString

public String getSequenceNextValString(String sequenceName)
Overrides:
getSequenceNextValString in interface Dialect

qualifyIndexName

public boolean qualifyIndexName()
RDMS does not support qualifing index names with the schema name.
Overrides:
qualifyIndexName in interface Dialect

supportsCascadeDelete

public boolean supportsCascadeDelete()
RDMS does not support Cascade Deletes. Need to review this in the future when support is provided.
Overrides:
supportsCascadeDelete in interface Dialect

supportsLimit

public boolean supportsLimit()
Overrides:
supportsLimit in interface Dialect

supportsLimitOffset

public boolean supportsLimitOffset()
Overrides:
supportsLimitOffset in interface Dialect

supportsOuterJoinForUpdate

public boolean supportsOuterJoinForUpdate()
Currently, RDMS-JDBC does not support ForUpdate. Need to review this in the future when support is provided.
Overrides:
supportsOuterJoinForUpdate in interface Dialect

supportsSequences

public boolean supportsSequences()
Overrides:
supportsSequences in interface Dialect

supportsUnionAll

public boolean supportsUnionAll()
Overrides:
supportsUnionAll in interface Dialect

supportsUniqueConstraintInCreateAlterTable

public boolean supportsUniqueConstraintInCreateAlterTable()
RDMS does not support adding Unique constraints via create and alter table.
Overrides:
