Processes Creates a separate process for every client connection, each with its own cache. Less resource use if the number of connections is low. A single process serves all connections, using threads be sufficient for the vast majority of cases. However, if you experience problems or if you have special needs not covered here, be sure to read the INSTALLATION NOTES chapter in the Release Notes. This “pipe” symbols (ASCII 124, in a pair with no space between). In SQL, the “+” symbol is an arithmetic operator and it will cause an error if you attempt to use it for concatenating strings. The following expression

timestamp not null Adding a NOT NULL column to an existing table that already contains records requires special care. This operation will be discussed in detail in the section Altering populated tables. 2.2 NULL is done with the ‘=’ operator, just like assigning values. You can also include NULL in an insert list or use it as input parameter to a stored procedure (both are special types of assignments). You cannot — and should not — use the comparison operator ‘=’ to test if something is NULL… • …but you can — and often must — use the assignment operator ‘=’ to set something to NULL. 2.4. Testing DISTINCTness

This is especially important if you are management 21 no special privileges in other databases. ◦ If it is a regular database, the grantee can control that database like they are SYSDBA, but again they have no special privileges in other SYSDBA or a co-admin, a global mapping that gives any Windows account access to databases — but no special privileges — under the same name. This is done with the following command: create global mapping
