Possible operation.command values (all need the table argument of the method call):
- getAllData: no additional instructions needed
- getFilteredData:
- operation.property (the column to search for the value),
- operation.searchQuery (the value to search for [will be sanitised by method])
- InnerJoin (Select values that match in both tables):
- operation.property (the column to search for the value),
- operation.searchQuery (the value to search for [will be sanitised by method])
- operation.selection (The columns of both tables to be selected, e.g. users.name, orders.id)
- operation.secondTable (The second table to perform Join operation with)
- operation.matchingParam (Which properties should be matched to get the data, e.g. order.user_id=users.id)
- LeftJoin (Select values in first table and return all corresponding values of second table):
- operation.property (the column to search for the value),
- operation.searchQuery (the value to search for [will be sanitised by method])
- operation.selection (The columns of both tables to be selected, e.g. users.name, orders.id)
- operation.secondTable (The second table to perform Join operation with)
- operation.matchingParam (Which properties should be matched to get the data, e.g. order.user_id=users.id)
- RightJoin (Select values in second table and return all corresponding values of first table):
- operation.property (the column to search for the value),
- operation.searchQuery (the value to search for [will be sanitised by method])
- operation.selection (The columns of both tables to be selected, e.g. users.name, orders.id)
- operation.secondTable (The second table to perform Join operation with)
- operation.matchingParam (Which properties should be matched to get the data, e.g. order.user_id=users.id)
- addData:
- operation.data (key-value pair with all data as values and column to insert into as key)
- updateData:
- operation.newValues (a object with keys being the column and value being the value to be inserted into that column, values are being
sanitised by the function)
- operation.property (the column to search for the value),
- operation.searchQuery (the value to search for [will be sanitised by method])
- checkDataAvailability:
- operation.property (the column to search for the value),
- operation.searchQuery (the value to search for [will be sanitised by method])
- fullCustomCommand:
- operation.query (the SQL instruction to be executed) --> NOTE: This command will not be sanitised, so use only with proper sanitisation!
