I’m a fresh student,I want to add a new cell or serveral cells into an array.
The Scidb version is 13.12,and it is running on ubuntu 12.04.
my aql statement:
AQL% create array test0 <val: int64> [i=0:10,10,0];
AQL% create array test1 <val: int64> [i=0:5,10,0];
AQL% insert into test1 ‘[1 2 3 4 5 6]’;
and then I insert data from test01into test1,my aql statement:
AQL% insert into test0 select val from test1;
then I get the following error:
UserException in file: src/query/ops/insert/LogicalInsert.cpp function: inferSchema line: 158
Error id: scidb::SCIDB_SE_INFER_SCHEMA::SCIDB_LE_DIMENSIONS_DONT_MATCH
Error description: Error during schema inferring. Dimensions ‘i’ and ‘i’ do not match.
Failed query id: 1100912174142
then I check the scidb-userguide-13.12.pdf document,in chapter9.1 it says:"array A and B must have compatible schemas."
So I think the problem is here.in test0 the “i” upper value is 10,but in test1 the “i” upper value is 5,they are not compatible.
But I want to put all the 6 values in test1 into test0,then add some new numbers into test1(from i=6–10).I don’t know how to do ?
In the scidb-userguide-13.1213.12.pdf Chapter9 ,it says"The AQL INSERT INTO statement lets you update attribute values and insert new cells into an existing
array. The new values come from another array with a compatible schema."
So I believe I can add new cells into an existing array,but I don’t know how to do,the problem has bothered me for weeks.
I just want to test the “insert” function to know whether it can help to make some add operation like sql.
Thanks!,I hope someone could help me.
