Method Detail

setRecordToStatement

public static void setRecordToStatement(PreparedStatement upload,
                                        int[] typesArray,
                                        org.apache.flink.types.Row row)
                                 throws SQLException

Adds a record to the prepared statement.

When this method is called, the output format is guaranteed to be opened.

WARNING: this may fail when no column types specified (because a best effort approach is attempted in order to insert a null value but it's not guaranteed that the JDBC driver handles PreparedStatement.setObject(pos, null))

Parameters:

upload - The prepared statement.

typesArray - The jdbc types of the row.

row - The records to add to the output.

Throws:

SQLException
