View source for Data Truncation Error

A data truncation error occurs when incoming data is too large to be stored. The error can occur for a number of reasons:
:* In a [[Multi Select Picklist]] or [[Multi Checkbox]] field, the combination of selected values could be larger than the maximum storage size for the field.
::* The default maximum size is 32 characters. 
::* If all values are selected, the number of characters required for N labels is the sum of the sizes of all N labels plus N-1 commas. 
::* That number can be reduced only if there are combinations of values that are never selected.
:* In a single-selection [[Picklist]], [[Global Picklist]], or [[Dependent Picklist]] a value available for selection might be longer than the maximum storage size specified for the field.
:* The combination of all fields defined in the record could be larger than the maximum size of a MySQL row (65,535 bytes).
