SybaseDialect

public SybaseDialect()

Method Detail

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

---

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

---

supportsForUpdate

public boolean supportsForUpdate()

Description copied from class: Dialect

Does this dialect support the FOR UPDATE syntax?

Overrides:

supportsForUpdate in class Dialect

Returns:

boolean

---

supportsIdentityColumns

public boolean supportsIdentityColumns()

Description copied from class: Dialect

Does this dialect support identity column key generation?

Overrides:

supportsIdentityColumns in class Dialect

Returns:

boolean

---

getIdentitySelectString

public String getIdentitySelectString()

Description copied from class: Dialect

The syntax that returns the identity value of the last insert, if identity column key generation is supported.

Overrides:

getIdentitySelectString in class Dialect

---

getIdentityColumnString

public String getIdentityColumnString()

Description copied from class: Dialect

The keyword used to specify an identity column, if identity column key generation is supported.

Overrides:

getIdentityColumnString in class Dialect

---

getNoColumnsInsertString

public String getNoColumnsInsertString()

Description copied from class: Dialect

The keyword used to insert a row without specifying any column values

Overrides:

getNoColumnsInsertString in class Dialect

---

appendIdentitySelectToInsert

public String appendIdentitySelectToInsert(String insertSQL)

Description copied from class: Dialect

Generate SQL to get the identifier of an inserted row. If the returned value is not null, the caller will prepare a statement from it, set SQL parameters just as it would for insertSQL, and execute it as a query which is expected to return the identifier of the inserted row. If the returned value is null, the caller will execute insertSQL as an update and then execute getIdentitySelectString() as a query. The default implementation (in this class) returns null.

Overrides:

appendIdentitySelectToInsert in class Dialect

Parameters:

insertSQL - a parameterized SQL statement to insert a row into a table.

Returns:

a SQL statement that has the same effect as insertSQL and also gets the identifier of the inserted row. Return null if this dialect doesn't support this feature.

                             String tableName)
