Method Detail

getProviderSqlType

public Object getProviderSqlType()

Returns the type provided by the stack on top of which the SQL Processor works.

Specified by:

getProviderSqlType in class SqlProviderType

Returns:

the provided type

getProviderSqlNullType

public Object getProviderSqlNullType()

Returns the type provided by the stack on top of which the SQL Processor works. It has to support null input/output values.

Specified by:

getProviderSqlNullType in class SqlProviderType

Returns:

the provided type

get

public Object get(ResultSet rs,
         String columnLabel)
           throws SQLException

Retrieves the value of the designated column in the current row of this ResultSet object as a Java type value.

Specified by:

get in interface JdbcSqlType

Parameters:

rs - a ResultSet instance

columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column

Returns:

the column value; if the value is SQL NULL, the value returned is null

Throws:

SQLException - if the columnLabel is not valid; if a database access error occurs or this method is called on a closed result set

set

public void set(PreparedStatement st,
       int index,
       Object value)
         throws SQLException

Sets the designated parameter to the given Java value. The JDBC driver converts this to the appropriate SQL type value.

Specified by:

set in interface JdbcSqlType

Parameters:

st - a PreparedStatement instance

index - the first parameter is 1, the second is 2, ...

value - the parameter value

Throws:

SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement

get

public Object get(CallableStatement cs,
         int index)
           throws SQLException

Retrieves the value of the designated parameter from CallableStatement object as a Java type value.

Specified by:

get in interface JdbcSqlType

Parameters:

cs - a CallableStatement instance

index - the first parameter is 1, the second is 2, ...

Returns:

the parameter value; if the value is SQL NULL, the value depends on the Java type

Throws:

SQLException - if the parameterIndex is not valid; if a database access error occurs or this method is called on a closed CallableStatement
