Hi,
I'm a beginner with sqliteand used to insert values in the fields of
datatype text with single quote and values of datatype integer without
single quote.
But I realized that sqlite accepts inserting both data types (text and
integer) with single quote without error.
For example the table:
CREATE TABLE foods(
id integer PRIMARY KEY,
type_id integer,
name text );
I can insert type_id without single quote:
INSERT INTO foods (name, type_id) VALUES ('Rice', 16);
And also with single quote:
INSERT INTO foods (name, type_id) VALUES ('Bean', '17');
select * FROM foods;
...
423 16 Rice
424 17 Bean
What are the consequences of inserting values in fields of datatype
integer with single quotes?
What are the effects on database size and performance?
Can I have problems in the future to make a query using logical
operators in these fields?
I'm making this question because it is simpler to implement in my
interface a routine to assemble a list of fields and values by inserting
single quotation marks in all elements of the list of values.
Otherwise I would have to identify the datatype of each field to decide
whether or not to include the quotes.
Thank you,
Markos
