21 -- arguments: table_name colname value
22 -- behavior: If the table table_name does not have a column colname with a data type equal to value, then the block will be executed
25 -- arguments: table_name colname value
26 -- behavior: If the table table_name does not have a row where colname = value, the block will be executed.
29 -- arguments: table_name colname value colname2 value2
30 -- behavior: If the table table_name does not have a row where colname = value AND colname2 = value2, the block will be executed.
33 -- arguments: table_name colname value colname2 value2 colname3 value3
34 -- behavior: If the table table_name does not have a row where colname = value AND colname2 = value2 AND colname3 = value3, the block will be executed.
37 -- arguments: table_name colname value colname2 value2 colname3 value3 colname4 value4
38 -- behavior: If the table table_name does not have a row where colname = value AND colname2 = value2 AND colname3 = value3 AND colname4 = value4, the block will be executed.
41 -- desc: This is a very specialized function to allow adding items to the list_options table to avoid both redundant option_id and title in each element.
42 -- arguments: table_name colname value colname2 value2 colname3 value3
43 -- behavior: The block will be executed if both statements below are true:
44 -- 1) The table table_name does not have a row where colname = value AND colname2 = value2.
45 -- 2) The table table_name does not have a row where colname = value AND colname3 = value3.
48 -- arguments: table_name colname value colname2 value2
49 -- behavior: If the table table_name does have a row where colname = value AND colname2 = value2, the block will be executed.
52 -- arguments: table_name colname value colname2 value2 colname3 value3
53 -- behavior: If the table table_name does have a row where colname = value AND colname2 = value2 AND colname3 = value3, the block will be executed.
56 -- desc: This function is most often used for dropping of indexes/keys.
57 -- arguments: table_name colname
58 -- behavior: If the table and index exist the relevant statements are executed, otherwise not.
61 -- desc: This function will allow adding of indexes/keys.
62 -- arguments: table_name colname
63 -- behavior: If the index does not exist, it will be created
66 -- all blocks are terminated with a #EndIf statement.
69 -- Custom function for creating Reaction List
71 -- #IfNotListOccupation
72 -- Custom function for creating Occupation List
74 -- #IfTextNullFixNeeded
75 -- desc: convert all text fields without default null to have default null.
79 -- desc: Execute SQL if the table has been created with given engine specified.
80 -- arguments: table_name engine
81 -- behavior: Use when engine conversion requires more than one ALTER TABLE
