HISTSIZE

Sets the amount of space to store the command history.

Sets the amount of space to store the command history. This value roughly approximates the number of commands vsql will store in its command history buffer. This value only impacts the number of lines stored by the current vsql session. It does not affect the history stored in the .vsql_history file.

The default value is 500.

Note

vsql multiplies the HISTSIZE value by 50 bytes (an approximation of the average length of a SQL statement) to arrive at the amount of memory to set aside for the command history. Depending on the actual length of your SQL statements, vsql may be able to store more or less commands than the value you set in HISTSIZE.
