Set variable from the result of a query
SYNOPSIS
var_query_set()
var variable to set from query
query start of query string to execute
query_end end of the query string to execute
DESCRIPTION
let @<var_name> = `<query>`
Execute the query and assign the first row of result to var as
a tab separated strings
Also assign each column of the result set to
variable "$<var_name>_<column_name>"
Thus the tab separated output can be read from $<var_name> and
and each individual column can be read as $<var_name>_<col_name>

sleep <seconds>

The difference between the sleep and real_sleep commands is that sleep
uses the delay from the --sleep command-line option if there is one.
(If the --sleep option is not given, the sleep command uses the delay
specified by its argument.) The real_sleep command always uses the
delay specified by its argument. The logic is that sometimes delays are
cpu-dependent, and --sleep can be used to set this delay. real_sleep is
used for cpu-independent delays.

This function will try to connect to the given server

This helps in situation when the client starts

It will only ignore connection errors during these retries.

Read one "line" from the file
SYNOPSIS
read_line
DESCRIPTION
This function actually reads several lines and adds them to the
buffer buf. It continues to read until it finds what it believes
is a complete query.
Normally that means it will read lines until it reaches the
"delimiter" that marks end of query. Default delimiter is ';'
The function should be smart enough not to detect delimiter's
found inside strings surrounded with '"' and '\'' escaped strings.
If the first line in a query starts with '#' or '-' this line is treated
as a comment. A comment is always terminated when end of line '\n' is
reached.
