Using DynamoDB with PartiQL, I am trying to select records using a global index:
SELECT *
FROM "My-Table.My-Index"
WHERE Foo = 'bar'
AND Timestamp >= 638014354649346173
AND Timestamp <= 638014355249346173
ORDER BY Timestamp
I am getting an exception of:
One or more errors occurred. (Statement wasn't well formed, can't be processed: Unexpected keyword)
Not sure what I am doing wrong here as I am new to PartiQL syntax.
It should be like this:
SELECT *
FROM "My-Table"."My-Index"
WHERE "Foo" = 'bar'
AND "Timestamp" >= 638014354649346173
AND "Timestamp" <= 638014355249346173
ORDER BY "Timestamp"

In my ADF pipeline I am trying to convert an output from my lookup activity to be in YYYY-MM-DD hh:mm:ss date format within the source query of a copy activity. The current output from my lookup activity is in YYYY-MM-DDThh:mm:ss format and I need to remove the 'T'.
I have tried using the dynamic content and formatDateTime functions but am having problems with the syntax. I am also using an SQL query to retrieve only the relevant data. The below is what I am
using as an input in the dynamic content query. I am able to get this to work, but I need to change '03/15/2018 12:00:00' to refer to the output of my lookup activity named LookupNewWaterMarkActivity.
SELECT *
FROM tableName
WHERE updatedDate >
'#{formatDateTime('03/15/2018 12:00:00', 'yyyy-MM-dd HH:mm:ss')}'
I have tried the below, but get the following error message:
'cannot fit package::output:any & { count, value } into the function parameter string. (6)'
SELECT *
FROM tableName
WHERE updatedDate >
'#{formatDateTime(activity('LookupNewWaterMarkActivity').output, 'yyyy-MM-dd HH:mm:ss')}'
Does anyone know how I can format the output of my activity within an SQL query any other way?
I am getting the below error when running the below code.
#concat('SELECT * FROM tableName WHERE sys_updated_on_value > ''',formatDateTime(activity('LookupNewWaterMarkActivity').output.value[0].sys_updated_on_value, 'yyyy-MM-dd HH:mm:ss'),'''')
Error code: FailToResolveParametersInExploratoryController

The parameters and expression cannot be resolved for schema operations.
Error Message: { "message": "ErrorCode=InvalidTemplate,

Use the lookup activity output (activity('Lookup1').output.value[0].columnName) value in your expression with column name as shown below to refer the lookup activity output in later activities.
Lookup activity output:
Copy activity:
Expression:
#concat('SELECT * FROM tb2 WHERE date1 > ''',formatDateTime(activity('Lookup1').output.value[0].date1, 'yyyy-MM-dd HH:mm:ss'),'''')
Update:
If you have enables firstRow property in your lookup, use the below expression:
#concat('SELECT * FROM tb2 WHERE date1 > ''',formatDateTime(activity('Lookup1').output.firstRow.date1, 'yyyy-MM-dd HH:mm:ss'),'''')
I have seen the dynamoDB doc for the PartiQL syntax:
SELECT expression [, ...]
FROM table[.index]
[ WHERE condition ] [ [ORDER BY key [DESC|ASC] , ...]
but in practice:
select * from dev .pk-all-index
where "pk" = 'config' AND ("brand" = 'tesla' OR contains("aliases", 'tesla.com'))
gives me the error:
An error occurred during the execution of the command.
ValidationException: Statement wasn't well formed, can't be processed:
Unexpected keyword
from "tablename"."indexname"
You might want to put the table name and index under quotes, individually.
SELECT * FROM "dev"."pk-all-index" WHERE "pk" = 'config' AND ("brand" = 'tesla' OR contains("aliases", 'tesla.com'))
I'm trying to get the recent document from my database, I have created this queryBuilder to get the Document obeject but it seems not working good when I add the clause Having.
This my query:
$qb = $this->createQueryBuilder('sm');
$qb
->andWhere('sm.supplier = :supplier')
->setParameter('supplier', $supplierId)
->andHaving('MAX(sm.createdAt)')
->groupBy('sm.id');
return $qb->getQuery()->getOneOrNullResult();
And this is the exception I'm getting:
{"code":500,"message":"[Syntax Error] line 0, col -1: Error: Expected
=, <, <=, <>, >, >=, !=, got end of string."}
This my DQL:
"SELECT sm FROM SupplierBundle\\Entity\\SupplierMedia sm WHERE sm.supplier = :supplier AND sm.type = :type GROUP BY sm.id HAVING MAX(sm.createdAt)"
HAVING expression defines conditions that will be applied on the result set after WHERE and GROUP BY.
If you just need to get last record from a table apply limit and order by.
To get the recent object for each supplier you could go with a self join approach
SELECT a
FROM SupplierBundle\Entity\SupplierMedia a
LEFT JOIN SupplierBundle\Entity\SupplierMedia b
WITH a.supplier = b.supplier
AND a.createdAt < b.createdAt
WHERE b.createdAt IS NULL
AND a.supplier = :supplier
AND a.type = :type
Doctrine Query Language get Max/Latest Row Per Group
I got assigned the following task.
Assume we have a table A structured with an id column and a date column.
Write a procedure in PL/SQL that: takes as parameters the table name (in our case A) and a date D, creates a backup table named A_bck containing only the records of A with dates < D and removes from the table A all the records inserted in A_bck.
Here there is my code.
Unluckily I get this error:
Error report -
ORA-00904: "MAY": invalid identifier
ORA-06512: at line 41
ORA-06512: at line 80
00904. 00000 - "%s: invalid identifier"
If I try to achieve the same result using a where condition on the id column instead that on the date one, I have no problems.
Where is the mistake? Am I implementing it completely in the wrong way?
The problem you have is that as you're executing dynamic sql you're query is built up as a string. Oracle does not know that the date you've given is actually a date, it is simply being treated as part of the string. To solve this you should be able to do the following:
my_query := 'CREATE TABLE ' || table_name_backup || ' AS (SELECT * FROM ' || table_name || ' WHERE table_date < to_date(''' || backup_date || '''))';
This should sort out your issue for you. As a side note, you will probably want to change your "table_exists" query, as table names are all stored in upper case, e.g.
SELECT COUNT(*) INTO table_exists FROM USER_TABLES WHERE TABLE_NAME = upper(my_table);
Edit: Further explanation following comment
To explain why you don't have the above problem when using integers, it is important to remember that using execute immediate simply executes the given string as an SQL query.
For example:
declare
x INTEGER := 1;
i integer;
my_query VARCHAR2(256);
begin
my_query := 'select 1 from dual where 1 = ' || x;
EXECUTE IMMEDIATE my_query INTO i;
end;
my_query in the above example would be executed as:
select 1 from dual where 1 = 1
which is perfectly valid sql. In your example however, you were ending up with something like this:
CREATE TABLE abaco_bck AS (SELECT * FROM abaco WHERE table_date < 27-MAY-17)
As it isn't wrapped in quotes, or explicitly converted to a date, the SQL engine is trying to subtract "MAY" from 27, but it doesn't know what "MAY" is.
One other thing to mention, is that for some operations you could use bind variables instead of quotes (although you can't for DDL) e.g.
declare
lToday DATE := SYSDATE;
i INTEGER;
my_query VARCHAR2(256);
begin
my_query := 'select 1 from dual where sysdate = :1';
EXECUTE IMMEDIATE my_query INTO i USING lToday;
end;
I am having trouble getting a block of pl/sql code to work. In the top of my procedure I get some data from my oracle apex application on what checkboxes are checked. Because the report that contains the checkboxes is generated dynamically I have to loop through the
APEX_APPLICATION.G_F01
list and generate a comma separated string which looks like this
v_list VARCHAR2(255) := (1,3,5,9,10);
I want to then query on that list later and place the v_list on an IN clause like so
SELECT * FROM users
WHERE user_id IN (v_list);
This of course throws an error. My question is what can I convert the v_list to in order to be able to insert it into a IN clause in a query within a pl/sql procedure?
If users is small and user_id doesn't contain commas, you could use:
SELECT * FROM users WHERE ',' || v_list || ',' LIKE '%,'||user_id||',%'
This query is not optimal though because it can't use indexes on user_id.
I advise you to use a pipelined function that returns a table of NUMBER that you can query directly. For example:
CREATE TYPE tab_number IS TABLE OF NUMBER;
/
CREATE OR REPLACE FUNCTION string_to_table_num(p VARCHAR2)
RETURN tab_number
PIPELINED IS
BEGIN
FOR cc IN (SELECT rtrim(regexp_substr(str, '[^,]*,', 1, level), ',') res
FROM (SELECT p || ',' str FROM dual)
CONNECT BY level <= length(str)
- length(replace(str, ',', ''))) LOOP
PIPE ROW(cc.res);
END LOOP;
END;
/
You would then be able to build queries such as:
SELECT *
FROM users
WHERE user_id IN (SELECT *
FROM TABLE(string_to_table_num('1,2,3,4,5'));
You can use XMLTABLE as follows
SELECT * FROM users
WHERE user_id IN (SELECT to_number(column_value) FROM XMLTABLE(v_list));
I have tried to find a solution for that too but never succeeded. You can build the query as a string and then run EXECUTE IMMEDIATE, see http://docs.oracle.com/cd/B19306_01/appdev.102/b14261/dynamic.htm#i14500.
That said, it just occurred to me that the argument of an IN clause can be a sub-select:
SELECT * FROM users
WHERE user_id IN (SELECT something FROM somewhere)
so, is it possible to expose the checkbox values as a stored function? Then you might be able to do something like
SELECT * FROM users
WHERE user_id IN (SELECT my_package.checkbox_func FROM dual)
Personally, i like this approach:
with t as (select 'a,b,c,d,e' str from dual)
--
select val
from t, xmltable('/root/e/text()'
passing xmltype('<root><e>' || replace(t.str,',','</e><e>')|| '</e></root>')
columns val varchar2(10) path '/'
)
