consider following code: function child() { echo $var } function parent() { local var=5 child } i've tested on machine , seems work wasn't able find definitive describing such usage of local variables. namely, when declare local variable in 1 function , function call other function, can use variable in latter (and nest deeper)? legal in bash , standard versions? bash uses dynamic scoping. value of var in child not determined child defined, called . if there no local definition in body of child , next place shell looks in body of function child called, , forth. local modifier creates variable in function local call, not affect value of variable enclosing scopes. is, though, visible enclosed scope. a () { echo "$var"; } b () { local var="local value"; a; } var="global value" # outputs "global value" b # outputs "local value"

can explain me, why code not working? select sum(`cash`) `cash`,count(*) `rows` `table_1` `login` = 'test' union select count(*) `rows2` `table_2` `login` = 'test'; in phpmyadmin see message: 1222 - used select statements have different number of columns and not solve problem. a union takes results of multiple select statements , presents them single result set. in order this, number of columns in individual select statements has same. to understand this, may format query bit: select sum(`cash`) `cash`, count(*) `rows` `table_1` `login` = 'test' union select count(*) `rows2` `table_2` `login` = 'test' your first query selecting 2 columns, cash , rows . second query selects 1 column, rows2 . note since union concatenating results, may call corresponding columns in each query same name. if don't have values want select second table, can substitute default value missing
