Nextval('foo') searches search path for foo Nextval('myschema.foo') operates on myschema.foo Nextval('"Foo"') operates on sequence Foo For example, the nextval(regclass) function takes a sequence relation's OID, so you could call it like this: This means you do not have to look up the object's OID by hand, but can just enter its name as a string literal. Many built-in PostgreSQL functions accept the OID of a table, or another kind of database object, and for convenience are declared as taking regclass (or the appropriate OID alias type). Both the function name and the argument type names could be schema-qualified, too. The output would look like "Foo"(integer,integer). For example, the OID of a function named Foo (with upper case F) taking two integer arguments could be entered as ' "Foo" ( int, integer ) '::regprocedure. Conversely, the output functions will use double quotes if needed to make the output be a valid SQL identifier. The input functions for these types allow whitespace between tokens, and will fold upper-case letters to lower case, except within double quotes this is done to make the syntax rules similar to the way object names are written in SQL. For regoperator, unary operators are identified by writing NONE for the unused operand. The regproc and regoper alias types will only accept input names that are unique (not overloaded), so they are of limited use for most uses regprocedure or regoperator are more appropriate. That value might be output as myschema.mytable, or just mytable, depending on the current search path. For example, myschema.mytable is acceptable input for regclass (if there is such a table). Similarly, casting a table's OID to regclass is handy for symbolic display of a numeric OID.Īll of the OID alias types for objects that are grouped by namespace accept schema-qualified names, and will display schema-qualified names on output if the object would not be found in the current search path without being qualified. The regclass input converter handles the table lookup according to the schema path setting, and so it does the “ right thing” automatically. A far more complicated sub-select would be needed to select the right OID if there are multiple tables named mytable in different schemas. While that doesn't look all that bad by itself, it's still oversimplified. WHERE attrelid = (SELECT oid FROM pg_class WHERE relname = 'mytable') SELECT * FROM pg_attribute WHERE attrelid = 'mytable'::regclass For example, to examine the pg_attribute rows related to a table mytable, one could write: The alias types allow simplified lookup of OID values for objects. These routines are able to accept and display symbolic names for system objects, rather than the raw numeric value that type oid would use. The OID alias types have no operations of their own except for specialized input and output routines. (Beware of possible signed-versus-unsigned confusion if you do this.) It can be cast to integer, however, and then manipulated using the standard integer operators. The oid type itself has few operations beyond comparison. Therefore, it is not large enough to provide database-wide uniqueness in large databases, or even in large individual tables. The oid type is currently implemented as an unsigned four-byte integer. There are also several alias types for oid, each named reg something. Type oid represents an object identifier. The cinematics cheat can cause Starcraft 2 clients to randomly crash which is likely part of the wider bugs but the framerate cap listed on the Starcraft 2 bugs and fixes page seems to help.Object identifiers (OIDs) are used internally by PostgreSQL as primary keys for various system tables. You then need to either start a new game or load a previously saved game to get achievement unlocking back again. To enable achievements again, start a new game or load a saved game.” “CHEAT PlayerName Achievements have been disabled due to cheat usage. This is very important to note if you use cheat codes in Starcraft 2 you will lose your ability to earn achievements while the cheat is activated for that game. Remember that cheats only work in Single Player, either in Custom Games, Tutorial, Campaign, or any other Single Player mode.
