Question

My table has 3 text fields: open_time_2, close_time_2, displayed_value (sample values are ‘5:45’, ‘4:15’, ”).
Need to update displayed_value with text ‘4:15 – 5:45’.
If I use the following query:

UPDATE mytable SET displayed_value=(close_time_2 + '-' open_time_2) 
WHERE close_time_2!=""

In result I am getting value ‘9.0’. What is wrong here?

Answer 1

You should use the SQLite concatenation operator, ||, rather than addition:

UPDATE mytable SET displayed_value=(close_time_2 || '-' || open_time_2)
WHERE close_time_2 != ""
