The developer confirms that the values were inserted as decimal literals but did not explicitly set a fixed-precision data type on the column. Which column data type definition is MOST likely causing this anomaly?

  • FLOAT

  • MONEY

  • NUMERIC(10,4)

Rotate by Objective
Questions cycle through each objective or domain in turn, helping you avoid long streaks of questions from the same area. You may see some repeat questions, but the distribution will be more balanced across topics.

Check or uncheck an objective to set which questions you will receive.
