public interface ColumnBinder

A helper to bind values from a wrapped Arrow vector to a JDBC PreparedStatement.

Method Summary

Modifier and Type	Method and Description
void	bind(PreparedStatement statement, int parameterIndex, int rowIndex) Bind the given row to the given parameter.
static ColumnBinder	forVector(FieldVector vector) Create a column binder for a vector, using the default JDBC type code for null values.
static ColumnBinder	forVector(FieldVector vector, Integer jdbcType) Create a column binder for a vector, overriding the JDBC type code used for null values.
int	getJdbcType() Get the JDBC type code used by this binder.
FieldVector	getVector() Get the vector used by this binder.

Method Detail

bind

void bind(PreparedStatement statement,
          int parameterIndex,
          int rowIndex)
   throws SQLException

Bind the given row to the given parameter.

Parameters:

statement - The statement to bind to.

parameterIndex - The parameter to bind to (1-indexed)

rowIndex - The row to bind values from (0-indexed)

Throws:

SQLException - if an error occurs

getJdbcType

int getJdbcType()

Get the JDBC type code used by this binder.

Returns:

A type code from Types.

getVector

FieldVector getVector()

Get the vector used by this binder.

forVector

static ColumnBinder forVector(FieldVector vector)

Create a column binder for a vector, using the default JDBC type code for null values.

forVector

static ColumnBinder forVector(FieldVector vector,
                              Integer jdbcType)

Create a column binder for a vector, overriding the JDBC type code used for null values.

Parameters:

vector - The vector that the column binder will wrap.

jdbcType - The JDBC type code to use (or null to use the default).
