void	alterTableDropColumn(DdlWrite writer, String tableName, String columnName)	It is rather complex to delete a column on SqlServer as there must not exist any references (constraints, default values, indices and foreign keys).
String	alterTableDropConstraint(String tableName, String constraintName)	Drop a unique constraint from the table.
String	alterTableDropForeignKey(String tableName, String fkName)	Return the drop foreign key clause.
String	alterTableDropUniqueConstraint(String tableName, String uniqueConstraintName)	Drop a unique constraint from the table (Sometimes this is an index).

dropTable

public String dropTable(String tableName)

Description copied from class: PlatformDdl

Return the drop table statement (potentially with if exists clause).

Overrides:

dropTable in class PlatformDdl

alterTableDropForeignKey

public String alterTableDropForeignKey(String tableName,
 String fkName)

Description copied from class: PlatformDdl

Return the drop foreign key clause.

Overrides:

alterTableDropForeignKey in class PlatformDdl

public String dropSequence(String sequenceName)

Description copied from class: PlatformDdl

Return the drop sequence statement (potentially with if exists clause).

Overrides:

dropSequence in class PlatformDdl

dropIndex

public String dropIndex(String indexName,
 String tableName,
 boolean concurrent)

Description copied from class: PlatformDdl

Return the drop index statement.

Overrides:

dropIndex in class PlatformDdl

alterTableAddUniqueConstraint

public String alterTableAddUniqueConstraint(String tableName,
 String uqName,
 String[] columns,
 String[] nullableColumns)

MsSqlServer specific null handling on unique constraints.

Overrides:

alterTableAddUniqueConstraint in class PlatformDdl

alterTableDropConstraint

public String alterTableDropConstraint(String tableName,
 String constraintName)

Description copied from class: PlatformDdl

Drop a unique constraint from the table.

Overrides:

alterTableDropConstraint in class PlatformDdl

alterTableDropUniqueConstraint

public String alterTableDropUniqueConstraint(String tableName,
 String uniqueConstraintName)

Drop a unique constraint from the table (Sometimes this is an index).

Overrides:

alterTableDropUniqueConstraint in class PlatformDdl

createSequence

public String createSequence(String sequenceName,
 DdlIdentity identity)

Generate and return the create sequence DDL.

Overrides:

createSequence in class PlatformDdl

alterColumn

public void alterColumn(DdlWrite writer,
 AlterColumn alter)

Description copied from class: PlatformDdl

Alter column setting (type, default value and not null constraint).

Used by MySql, SQL Server, and HANA as these require all column attributes to be set together.

Overrides:

alterColumn in class PlatformDdl

addTableComment

public void addTableComment(DdlBuffer apply,
 String tableName,
 String tableComment)

Add table comment as a separate statement (from the create table statement).

Overrides:

addTableComment in class PlatformDdl

addColumnComment

public void addColumnComment(DdlBuffer apply,
 String table,
 String column,
 String comment)

Add column comment as a separate statement.

Overrides:

addColumnComment in class PlatformDdl

alterTableDropColumn

public void alterTableDropColumn(DdlWrite writer,
 String tableName,
 String columnName)

It is rather complex to delete a column on SqlServer as there must not exist any references (constraints, default values, indices and foreign keys). That's why we call a user stored procedure here

Overrides:

alterTableDropColumn in class PlatformDdl

generateProlog

public void generateProlog(DdlWrite writer)

This writes the multi value datatypes needed for MultiValueBind.

Overrides:

generateProlog in class PlatformDdl

ifObjectExists

public static String ifObjectExists(String object,
 String objectType)
