Count Rows (LCC.db.count)

Signature​

count, err = LCC.db.count(name, conditions?, timeout?)

Parameters​

  • name
    String. Table name. Must be non-empty and no longer than 256 bytes.
  • conditions
    Table, optional. Equality conditions combined with AND; counts all rows when omitted.
  • timeout
    Number, optional. Request timeout in seconds, default 60.

Returns​

  • count
    Number. Number of matching rows; nil on failure.
  • err
    String or nil. Error description when the call fails.

Notes​

Returns the number of matching rows, using the same condition semantics as list.
Unknown tables or columns produce errors that are returned to the caller.

Example​

local total, err = LCC.db.count("tasks", { Status = "Idle" })
if total then
    LCC.log(1, "Idle tasks", total)
end
