Constructor Detail

MicrosoftSqlServerDialect

public MicrosoftSqlServerDialect(Connection connection)
                          throws SQLException

Creates a MicrosoftSqlServerDialect.

Parameters:

connection - Connection

Throws:

SQLException

Method Detail

generateInline

public String generateInline(List<String> columnNames,
                             List<String> columnTypes,
                             List<String[]> valueList)

Description copied from interface: Dialect

Generates a SQL statement to represent an inline dataset.

For example, for Oracle, generates

 SELECT 1 AS FOO, 'a' AS BAR FROM dual
 UNION ALL
 SELECT 2 AS FOO, 'b' AS BAR FROM dual
 

For ANSI SQL, generates:

 VALUES (1, 'a'), (2, 'b')
 

Specified by:

generateInline in interface Dialect

Overrides:

generateInline in class JdbcDialectImpl

Parameters:

columnNames - List of column names

columnTypes - List of column types ("String" or "Numeric")

valueList - List of rows values

Returns:

SQL string

requiresAliasForFromQuery

public boolean requiresAliasForFromQuery()

Description copied from interface: Dialect

Returns whether this Dialect requires subqueries in the FROM clause to have an alias.

Specified by:

requiresAliasForFromQuery in interface Dialect

Overrides:

requiresAliasForFromQuery in class JdbcDialectImpl

Returns:

whether dialewct requires subqueries to have an alias

See Also:

Dialect.allowsFromQuery()

requiresUnionOrderByOrdinal

public boolean requiresUnionOrderByOrdinal()

Description copied from interface: Dialect

Returns true if this dialect allows only integers in the ORDER BY clause of a UNION (or other set operation) query.

For example, SELECT x, y + z FROM t
UNION ALL
SELECT x, y + z FROM t
ORDER BY 1, 2 is allowed but SELECT x, y, z FROM t
UNION ALL
SELECT x, y, z FROM t
ORDER BY x is not.

Teradata is an example of a dialect with this restriction.

Specified by:

requiresUnionOrderByOrdinal in interface Dialect

Overrides:

requiresUnionOrderByOrdinal in class JdbcDialectImpl

Returns:

whether this dialect allows only integers in the ORDER BY clause of a UNION (or other set operation) query

quoteBooleanLiteral

public void quoteBooleanLiteral(StringBuilder buf,
                                String value)

Description copied from interface: Dialect

Appends to a buffer a boolean literal.

In the default dialect, boolean literals are printed as is.

Specified by:

quoteBooleanLiteral in interface Dialect

Overrides:

quoteBooleanLiteral in class JdbcDialectImpl

Parameters:

buf - Buffer to append to

value - Literal

quoteDateLiteral

protected void quoteDateLiteral(StringBuilder buf,
                                String value,
                                Date date)

Description copied from class: JdbcDialectImpl

Helper method for JdbcDialectImpl.quoteDateLiteral(StringBuilder, String).

Overrides:

quoteDateLiteral in class JdbcDialectImpl

Parameters:

buf - Buffer to append to

value - Value as string

date - Value as date

quoteTimestampLiteral

protected void quoteTimestampLiteral(StringBuilder buf,
                                     String value,
                                     Timestamp timestamp)

Overrides:

quoteTimestampLiteral in class JdbcDialectImpl
