Method Detail

toUpperCase

public java.lang.String toUpperCase(java.lang.String in)
This method is used to ignore case. Problem is that Informix does not have an UPPER function. So the best would be to do nothing.
Overrides:
toUpperCase in class DB
Parameters:
in - The string to transform to upper case.
Returns:
The upper case string.

ignoreCase

public java.lang.String ignoreCase(java.lang.String in)
This method is used to ignore case. Problem is that Informix does not have an UPPER function. So the best would be to do nothing.
Overrides:
ignoreCase in class DB
Parameters:
in - The string whose case to ignore.
Returns:
The string in a case that can be ignored.

getStringDelimiter

public char getStringDelimiter()
Gets the string delimiter (usually '\'').
Overrides:
getStringDelimiter in class DB
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 obj)
Description copied from class: DB
Returns SQL used to get the most recently inserted primary key. Databases which have no support for this return null.
Overrides:
getIDMethodSQL in class DB
See Also:
DB.getIDMethodSQL(Object obj)

lockTable

public void lockTable(java.sql.Connection con,
                      java.lang.String table)
               throws java.sql.SQLException
The method is used to lock a table.
Overrides:
lockTable in class DB
Parameters:
con - The JDBC connection to use.
table - The name of the table to lock.
Throws:
java.sql.SQLException -  

unlockTable

public void unlockTable(java.sql.Connection con,
                        java.lang.String table)
                 throws java.sql.SQLException
The method is used to unlock a table.
Overrides:
unlockTable in class DB
Parameters:
con - The JDBC connection to use.
table - The name of the table to unlock.
Throws:
java.sql.SQLException -
