/* SQL Database API
|
|
* By the AMX Mod X Development Team
|
|
* Notes - Read the comments! Make sure your plugins use
|
|
* nice ANSI SQL and don't use database column names like "key"
|
|
* otherwise this API will be a nightmare
|
|
* Never do error checking with the not operator! This is bad:
|
|
* if (!dbi_query())
|
|
* You should do:
|
|
* ret = dbi_query()
|
|
* if (ret < 0)
|
|
* This is because DBI functions can and will return negative numbers
|
|
* Negative numbers evaluate to "true" in AMX.
