Functions

OID OidType OID(size_t colNum): Returns column Oid
cmdStatus string cmdStatus(): Returns the command status tag from the SQL command that generated the PGresult Commonly this is just the name of the command, but it might include additional data such as the number of rows processed.
cmdTuples string cmdTuples(): * Returns the number of rows affected by the SQL command. * This function returns a string containing the number of rows affected by the SQL statement * that generated the Answer. This function can only be used following the execution of * a SELECT, CREATE TABLE AS, INSERT, UPDATE, DELETE, MOVE, FETCH, or COPY statement, * or an EXECUTE of a prepared query that contains an INSERT, UPDATE, or DELETE statement. * If the command that generated the Anwser was anything else, cmdTuples returns an empty string.
columnCount size_t columnCount(): Returns column count
columnExists bool columnExists(string columnName): Returns true if the column exists, false if not
columnFormat ValueFormat columnFormat(size_t colNum): Returns column format
columnName string columnName(size_t colNum): Returns column name by field number
columnNum size_t columnNum(string columnName): Returns column number by field name
isArray bool isArray(size_t colNum): Checks if column type is array
length size_t length(): Returns row count
nParams uint nParams(): Returns the number of parameters of a prepared statement. This function is only useful when inspecting the result of describePrepared. For other types of queries it will return zero.
opIndex immutable(Row) opIndex(size_t row): Returns row of cells
paramType OidType paramType(T paramNum): Returns the data type of the indicated statement parameter. Parameter numbers start at 0. This function is only useful when inspecting the result of describePrepared. For other types of queries it will return zero.
toString string toString()

status ExecStatusType status(): Returns the result status of the command.
