Deletes the {@link ColumnInfo} with given index.
com.heatonresearch.aifh.normalize.DataSet.deleteColumn()
Delete the specified column. @param col The column to delete.
com.netflix.astyanax.ColumnListMutation.deleteColumn()
Insert a delete column mutation. Note that you must be careful when deleting and adding the same column on the same mutation. For the most part all columns will have the same timestamp so only the first operation will be performed. @param columnName @return
de.ambits.csvmaster.service.CsvService.deleteColumn()
de.ambits.csvmaster.service.ICsvService.deleteColumn()
Removes the given column from the csv content. @param columnName The name of the column. @param event The ExecutionEvent to get the data from. @throws ExecutionException Thrown if exectuion fails.
org.apache.hadoop.hbase.HBaseAdmin.deleteColumn()
Delete a column from a table @param tableName name of table @param columnName name of column to be deleted @throws IOException
org.apache.hadoop.hbase.client.Admin.deleteColumn()
Delete a column from a table. Asynchronous operation. @param tableName name of table @param columnName name of column to be deleted @throws IOException if a remote or network exception occurs
org.apache.hadoop.hbase.client.Delete.deleteColumn()
Delete the latest version of the specified column. This is an expensive call in that on the server-side, it first does a get to find the latest versions timestamp. Then it adds a delete using the fetched cells timestamp. @param family family name @param qualifier column qualifier @return this for invocation chaining
org.apache.hadoop.hbase.client.HBaseAdmin.deleteColumn()
Delete a column from a table. Asynchronous operation. @param tableName name of table @param columnName name of column to be deleted @throws IOException if a remote or network exception occurs
org.apache.hadoop.hbase.master.MasterFileSystem.deleteColumn()
Delete column of a table @param tableName @param familyName @return Modified HTableDescriptor with requested column deleted. @throws IOException
org.kiji.schema.KijiTableWriter.deleteColumn()
org.rhq.core.db.DatabaseType.deleteColumn()
Deletes a column. @param conn @param table @param column @throws SQLException
org.scale7.cassandra.pelops.Mutator.deleteColumn()
