Query params

Param Description Default value Example Value
where Logical Expression (colName,eq,colValue)~or(colName2,gt,colValue2)
Usage: Comparison operators
Usage: Logical operators
limit Number of rows to get(SQL limit value) 10 20
offset Offset for pagination(SQL offset value) 0 20
sort Sort column name, where use - as prefix for descending sort column_name
fields Required column names in result * column_name_1,column_name_2

Comparison operators

eq      -   '='         -  (colName,eq,colValue)
not     -   '!='        -  (colName,ne,colValue)
gt      -   '>'         -  (colName,gt,colValue)
