Returns:
The delimeter.

getIDMethodType

public java.lang.String getIDMethodType()
Description copied from class: DB
Returns the constant from the {@see IDMethod} interface denoting which type of primary key generation method this type of RDBMS uses.
Overrides:
getIDMethodType in class DB
See Also:
DB.getIDMethodType()

getIDMethodSQL

public java.lang.String getIDMethodSQL(java.lang.Object sequenceName)
Returns the next key from a sequence. Uses the following implementation:

Overrides:
getIDMethodSQL in class DB
Parameters:
sequenceName - The name of the sequence (should be of type String).
Returns:
SQL to retreive the next database key.
See Also:
DB.getIDMethodSQL(Object)

lockTable

public void lockTable(java.sql.Connection con,
