Method Detail

supportsIfExistsBeforeTableName

public boolean supportsIfExistsBeforeTableName()

Description copied from class: Dialect

For dropping a table, can the phrase "if exists" be applied before the table name?

NOTE : Only one or the other (or neither) of this and Dialect.supportsIfExistsAfterTableName() should return true

Overrides:

supportsIfExistsBeforeTableName in class Dialect

Returns:

true if the "if exists" can be applied before the table name

supportsIfExistsBeforeConstraintName

public boolean supportsIfExistsBeforeConstraintName()

Description copied from class: Dialect

For dropping a constraint with an "alter table", can the phrase "if exists" be applied before the constraint name?

NOTE : Only one or the other (or neither) of this and Dialect.supportsIfExistsAfterConstraintName() should return true

Overrides:

supportsIfExistsBeforeConstraintName in class Dialect

Returns:

true if the "if exists" can be applied before the constraint name

getDropSequenceString

public String getDropSequenceString(String sequenceName)

Description copied from class: Dialect

Typically dialects which support sequences can drop a sequence with a single command. This is convenience form of Dialect.getDropSequenceStrings(java.lang.String) to help facilitate that.

Dialects which support sequences and can drop a sequence in a single command need *only* override this method. Dialects which support sequences but require multiple commands to drop a sequence should instead override Dialect.getDropSequenceStrings(java.lang.String).

Overrides:

getDropSequenceString in class SQLServer2012Dialect

Parameters:

sequenceName - The name of the sequence

Returns:

The sequence drop commands

getDropSchemaCommand

public String[] getDropSchemaCommand(String schemaName)

Description copied from class: Dialect

Get the SQL command used to drop the named schema

Overrides:

getDropSchemaCommand in class Dialect

Parameters:

schemaName - The name of the schema to be dropped.

Returns:

The drop commands

getAddColumnString

public String getAddColumnString()

Description copied from class: Dialect

The syntax used to add a column to a table (optional).

Overrides:

getAddColumnString in class Dialect

Returns:

The "add column" fragment.

getNullColumnString

public String getNullColumnString()

Description copied from class: Dialect

The keyword used to specify a nullable column.

Overrides:

getNullColumnString in class Dialect

Returns:

String

qualifyIndexName

public boolean qualifyIndexName()

Description copied from class: Dialect

Do we need to qualify index names with the schema name?

Overrides:

qualifyIndexName in class Dialect

Returns:

boolean

getForUpdateString

public String getForUpdateString()

Description copied from class: Dialect

Get the string to append to SELECT statements to acquire locks for this dialect.

Overrides:

getForUpdateString in class Dialect

Returns:

The appropriate FOR UPDATE clause string.

applyLocksToSql

public String applyLocksToSql(String sql,
                              LockOptions aliasedLockOptions,
                              Map<String,String[]> keyColumnNames)

Description copied from class: Dialect

Modifies the given SQL by applying the appropriate updates for the specified lock modes and key columns.

The behavior here is that of an ANSI SQL SELECT FOR UPDATE. This method is really intended to allow dialects which do not support SELECT FOR UPDATE to achieve this in their own fashion.

Overrides:

applyLocksToSql in class Dialect

Parameters:

sql - the SQL string to modify

aliasedLockOptions - lock options indexed by aliased table names.

keyColumnNames - a map of key columns indexed by aliased table names.

Returns:

the modified SQL string.

registerResultSetOutParameter

public int registerResultSetOutParameter(CallableStatement statement,
                                         int col)
                                  throws SQLException

Description copied from class: Dialect

Registers a parameter (either OUT, or the new REF_CURSOR param type available in Java 8) capable of returning ResultSet *by position*. Pre-Java 8, registering such ResultSet-returning parameters varied greatly across database and drivers; hence its inclusion as part of the Dialect contract.

Overrides:

registerResultSetOutParameter in class Dialect

Parameters:

statement - The callable statement.

col - The bind position at which to register the output param.

Returns:

The number of (contiguous) bind positions used.

Throws:

SQLException - Indicates problems registering the param.

getResultSet

public ResultSet getResultSet(CallableStatement ps)
                       throws SQLException

Description copied from class: Dialect

Given a callable statement previously processed by Dialect.registerResultSetOutParameter(java.sql.CallableStatement, int), extract the ResultSet from the OUT parameter.

Overrides:

getResultSet in class Dialect

Parameters:

ps - The callable statement.

Returns:

The extracted result set.

Throws:

SQLException - Indicates problems extracting the result set.

supportsCurrentTimestampSelection

public boolean supportsCurrentTimestampSelection()

Description copied from class: Dialect

Does this dialect support a way to retrieve the database's current timestamp value?

Overrides:

supportsCurrentTimestampSelection in class Dialect

Returns:

True if the current timestamp can be retrieved; false otherwise.

isCurrentTimestampSelectStringCallable

public boolean isCurrentTimestampSelectStringCallable()

Description copied from class: Dialect

Should the value returned by Dialect.getCurrentTimestampSelectString() be treated as callable. Typically this indicates that JDBC escape syntax is being used...

Overrides:

isCurrentTimestampSelectStringCallable in class Dialect

Returns:

True if the Dialect.getCurrentTimestampSelectString() return is callable; false otherwise.

getDefaultMultiTableBulkIdStrategy

public MultiTableBulkIdStrategy getDefaultMultiTableBulkIdStrategy()

Overrides:

Optional operation.

Overrides:

getSelectGUIDString in class Dialect

Returns:

The appropriate command.

supportsEmptyInList

public boolean supportsEmptyInList()

Description copied from class: Dialect

Does this dialect support empty IN lists?

supportsUnionAll

public boolean supportsUnionAll()

Description copied from class: Dialect
