Constructor & Destructor Documentation

org.objectweb.cjdbc.common.sql.DropRequest.DropRequest (  String  sqlQuery,
boolean  escapeProcessing,
int  timeout,
String  lineSeparator,
DatabaseSchema  schema,
int  granularity,
boolean  isCaseSensitive
)  throws SQLException
 

Creates a new DropRequest instance. The caller must give an SQL request, without any leading or trailing spaces and beginning with 'drop table ' (it will not be checked).

If the syntax is incorrect an exception is thrown.

Parameters:
sqlQuery a String value
escapeProcessing should the driver to escape processing before sending to the database ?
timeout an int value
lineSeparator the line separator used in the query
schema a DatabaseSchema value
granularity parsing granularity as defined in ParsingGranularities
isCaseSensitive true if parsing is case sensitive
Exceptions:
SQLException if an error occurs

org.objectweb.cjdbc.common.sql.DropRequest.DropRequest (  String  sqlQuery,
boolean  escapeProcessing,
int  timeout,
String  lineSeparator
) 
 

Creates a new DropRequest instance. The caller must give an SQL request, without any leading or trailing spaces and beginning with 'create table ' (it will not be checked).

The request is not parsed but it can be done later by a call to parse(DatabaseSchema, int, boolean).

Parameters:
sqlQuery the SQL request
escapeProcessing should the driver to escape processing before sending to the database ?
timeout an int value
lineSeparator the line separator used in the query
