Where
To filter table's rows by any value you can use where clause.
Each item of where clause should return boolean value.
Main format of where clause looks like bellow:
const query = {
filter: {
where: {
operator: FDBOperators,
args: Array<FDBWhere | FDBWhereArgs>
}
}
}
See types descriptions of FDB Operator, FDB Where and FDB Where Arguments for more details.
operator: string: one of listed values:
Logic Operators

&, and |
(a = 5) AND (b = 6) |
|, or |

notILike |
NOT ILIKE '%hat' |
startsWith |
LIKE 'hat%' |
endsWith |
LIKE '%hat' |
substring |
LIKE '%hat%' |
regexp |
REGEXP/~ '^[h | a | t]' |
notRegexp |
NOT REGEXP/~ '^[h | a | t]' |
iRegexp |
~* '^[h | a | t]' |
notIRegexp |
!~* '^[h | a | t]' |
between |
BETWEEN 6 AND 10 |
notBetween |
NOT BETWEEN 11 AND 15 |
is |
IS NULL |
overlap |
&& [1, 2] (PG array overlap operator) |
contains |
@> [1, 2] (PG array contains operator) |
contained |
<@ [1, 2] (PG array contained by operator) |
any |
ANY ARRAY[2, 3]::INTEGER |
all |
> ALL (SELECT 1) |
args: Array<FDBWhere | FDBWhereArgs>:
{
args: ['id', 3]
}
Where id is column name and 3 is value
const query = {
filter: {
where: {
operator: '=',
args: [ 'id', 2 ] // id = 2
}
},
context: {
tableName: '245ce633-796f-4dfa-ae6f-4b2762adbf44'
}
}
This query will be converted to SQL statement:
SELECT * FROM "245ce633-796f-4dfa-ae6f-4b2762adbf44" WHERE "id" = 2;
