Method Detail

getConnection

protected abstract Connection getConnection()
                                     throws SQLException

Throws:

SQLException

setMultipleResults

public void setMultipleResults(String value)

It appears that some commercial DBMSs like Oracle and Informix are broken in that they don't follow the JDBC standard and calls to getUpdateCount after getMoreResults result either in an exception (Informix) or return the same value (i.e. not -1) (Oracle). In addition, this feature is only useful with stored procedures. Hence we disable it per default.

getMultipleResults

public boolean getMultipleResults()

getProperties

public Properties getProperties()

setProperty

                        Object value)

setUser

setPassword

public void setPassword(String password)

setAutoCommit

public void setAutoCommit(boolean autocommit)
                   throws SQLException

Throws:

createQuery

public AbstractEsqlQuery createQuery(String type,
                                     String queryString)
                              throws SQLException

Factory method for creating an EsqlQuery object. If type is set to "" or "auto" it will try to find type from the JDBC connection URL. If this does not succeed the generic JDBC type will be assumed. (This type does not work for some databases like mssql though)

Parameters:

type - {sybase|postgresql|mysql|oracle|jdbc}

queryString -

Returns:

implementation of the AbstractEsqlQuery

Throws:

SQLException
