Method Detail

indexOf

public void indexOf(SQLBuffer buf,
                    FilterValue str,
                    FilterValue find,
                    FilterValue start)

Description copied from class: DBDictionary

Invoke this database's indexOf function.

Overrides:

indexOf in class DBDictionary

Parameters:

buf - the SQL buffer to write the indexOf invocation to

str - a query value representing the target string

find - a query value representing the search string

start - a query value representing the start index, or null to start at the beginning

substring

public void substring(SQLBuffer buf,
                      FilterValue str,
                      FilterValue start,
                      FilterValue length)

Description copied from class: DBDictionary

Invoke this database's substring function. Numeric parameters are inlined if possible. This is to handle grouping by SUBSTRING - most databases do not allow parameter binding in this case.

Overrides:

substring in class DBDictionary

Parameters:

buf - the SQL buffer to write the substring invocation to

str - a query value representing the target string

start - a query value representing the start index

length - a query value representing the length of substring, or null for none
