- the value of that column as a byte array
public abstract int getColumnCount ()
Returns total number of columns
Returns
- number of columns
public abstract int getColumnIndex (String columnName)
Returns the zero-based index for the given column name, or -1 if the column doesn't exist.
Parameters
| columnName | the name of the target column |
|---|
