Field Detail cursor Cursor cursor(Code) Constructor Detail ResultSetMetaData public ResultSetMetaData(Cursor cursor)(Code) Method Detail getCatalogName public String getCatalogName(int column) throws SQLException(Code) QED doesn't support catalogs. getColumnClassName public String getColumnClassName(int column) throws SQLException(Code) Return the fully qualified class name of the Java class to which the specified column will be mapped Parameters:   column - the column number the column's class name exception:   SQLException - may be thrown getColumnCount public int getColumnCount() throws SQLException(Code) Return the number of columns in the ResultSet. the number of columns in the ResultSet. exception:   SQLException - may be thrown getColumnDisplaySize public int getColumnDisplaySize(int column) throws SQLException(Code) Return the normal maximum width in characters of the values in the specified column Parameters:   column - the column number the maximum display size of a value in this column exception:   SQLException - may be thrown getColumnLabel public String getColumnLabel(int column) throws SQLException(Code) Return the shortest possible name for this column, such that the name is unique within this ResultSet object. Parameters:   column - the column number the column label exception:   SQLException - may be thrown getColumnName public String getColumnName(int column) throws SQLException(Code) Return the shortest possible name for this column, such that the name is unique within this ResultSet object. Parameters:   column - the column number the column name exception:   SQLException - may be thrown getColumnType public int getColumnType(int column) throws SQLException(Code) Return the JDBC type of this column Parameters:   column - the column number the column's JDBC type exception:   SQLException - may be thrown getColumnTypeName public String getColumnTypeName(int column) throws SQLException(Code) Return the SQL type name of this column Parameters:   column - the column number the column's SQL type exception:   SQLException - may be thrown getPrecision public int getPrecision(int column) throws SQLException(Code) Return the maximum precision of this column, or -1 if this column is not a numeric type. Parameters:   column - the column number the column's maximum precision exception:   SQLException - may be thrown getScale public int getScale(int column) throws SQLException(Code) Return the scale of this column, or -1 if this column is not a numeric type Parameters:   column - the column number the column's scale exception:   SQLException - may be thrown getSchemaName public String getSchemaName(int column) throws SQLException(Code) Return the schema name for the table from which this column is derived. This function works for normal columns, but returns the empty string for computed columns. Parameters:   column - the column number the column's table's schema's name exception:   SQLException - may be thrown getTableName public String getTableName(int column) throws SQLException(Code) Return name of the table from which this column is derived. Parameters:   column - the column number the column's table's name exception:   SQLException - may be thrown isAutoIncrement public boolean isAutoIncrement(int column) throws SQLException(Code) Return true if this is an auto-increment type. Parameters:   column - the column number false exception:   SQLException - may be thrown isCaseSensitive public boolean isCaseSensitive(int column) throws SQLException(Code) Return true if this column is case-sensitive. QED always returns false. Parameters:   column - the column number false exception:   SQLException - may be thrown isCurrency public boolean isCurrency(int column) throws SQLException(Code) Return true if this column is a cash value. QED always returns false. Parameters:   column - the column number false exception:   SQLException - may be thrown isDefinitelyWritable public boolean isDefinitelyWritable(int column) throws SQLException(Code) Return true if this column is definitely writable Parameters:   column - the column number true if this column is writable exception:   SQLException - may be thrown isNullable public int isNullable(int column) throws SQLException(Code) Return the JDBC 'nullability' state for this column Parameters:   column - the column number if this column can contain NULLs exception:   SQLException - may be thrown isReadOnly public boolean isReadOnly(int column) throws SQLException(Code) Return true if this column is not writable Parameters:   column - the column number true if this column is read-only exception:   SQLException - may be thrown isSearchable public boolean isSearchable(int column) throws SQLException(Code) Return true if the column can be used in a WHERE clause. QED always returns true Parameters:   column - the column number true exception:   SQLException - may be thrown isSigned public boolean isSigned(int column) throws SQLException(Code) Return true if this column contains a signed number. In QED, this is true for all numeric types and for intervals. Parameters:   column - the column number true if this column contains a signed number exception:   SQLException - may be thrown isWritable public boolean isWritable(int column) throws SQLException(Code) Return true if this column is writable.
