Constructor Detail

CreateRequest

public CreateRequest(java.lang.String sqlQuery,
                     boolean escapeProcessing,
                     int timeout,
                     DatabaseSchema schema,
                     int granularity,
                     boolean isCaseSensitive)
              throws java.sql.SQLException

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

If the syntax is incorrect an exception is thrown.

Parameters:

sqlQuery - the SQL request

escapeProcessing - should the driver to escape processing before sending to the database?

timeout - an int value

schema - a DatabaseSchema value

granularity - parsing granularity as defined in ParsingGranularities

isCaseSensitive - true if parsing is case sensitive

Throws:

java.sql.SQLException - if an error occurs

CreateRequest

public CreateRequest(java.lang.String sqlQuery,
                     boolean escapeProcessing,
                     int timeout)

Creates a new CreateRequest 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

parse(org.objectweb.cjdbc.sql.schema.DatabaseSchema, int, boolean)

Method Detail

parse

public void parse(DatabaseSchema schema,
                  int granularity,
                  boolean isCaseSensitive)
           throws java.sql.SQLException

Description copied from class: AbstractRequest

Parses the SQL request and extract the selected columns and tables given the DatabaseSchema of the database targeted by this request.

An exception is thrown when the parsing fails. Warning, this method does not check the validity of the request. In particular, invalid request could be parsed without throwing an exception. However, valid SQL request should never throw an exception.

Specified by:

parse in class AbstractRequest

Parameters:

schema - a DatabaseSchema value

granularity - parsing granularity as defined in ParsingGranularities

isCaseSensitive - true if parsing must be case sensitive

Throws:

java.sql.SQLException - if the parsing fails
