[GitHub] [arrow-datafusion] mvanschellebeeck opened a new issue, #4396: Support CREATE TABLE table_name(...schema_fields)
mvanschellebeeck opened a new issue, #4396:
URL: https://github.com/apache/arrow-datafusion/issues/4396
**Describe the solution you'd like**
Support the CREATE TABLE expression, e.g.
`CREATE TABLE t1(a INTEGER, b INTEGER, c INTEGER, d INTEGER, e INTEGER);`
Executing this with `datafusion-cli` shows:
```bash
DataFusion CLI v14.0.0
❯ CREATE TABLE t1(a INTEGER, b INTEGER, c INTEGER, d INTEGER, e INTEGER);
NotImplemented("Only `CREATE TABLE table_name AS SELECT ...` statement is supported")
```
**Additional context**
The ability to create a table with one statement and then insert values into it throughout a sessions forms the basis of a lot of [sqllogictests](https://www.sqlite.org/sqllogictest/file?name=test/select1.test&ci=tip) we want to incorporate into testing. See https://github.com/apache/arrow-datafusion/issues/4248

An example of a set of queries we'd like to execute are:
```sql
statement ok
CREATE TABLE t1(a INTEGER, b INTEGER, c INTEGER, d INTEGER, e INTEGER)
statement ok
INSERT INTO t1(e,c,b,d,a) VALUES(103,102,100,101,104)
statement ok
INSERT INTO t1(a,c,d,e,b) VALUES(107,106,108,109,105)
...
statement ok
INSERT INTO t1(e,c,a,d,b) VALUES(177,176,179,178,175)
statement ok
INSERT INTO t1(b,e,a,d,c) VALUES(181,180,182,183,184)
statement ok
INSERT INTO t1(c,a,b,e,d) VALUES(187,188,186,189,185)
statement ok
INSERT INTO
statement ok
INSERT INTO t1(e,c,b,a,d) VALUES(242,244,240,243,241)
statement ok
INSERT INTO t1(e,d,c,b,a) VALUES(246,248,247,249,245)
query I nosort
SELECT CASE WHEN c>(SELECT avg(c) FROM t1) THEN a*2 ELSE b*10 END
FROM t1
ORDER BY 1
----
30 values hashing to 3c13dee48d9356ae19af2515e05e6b54
```
see [here](https://www.sqlite.org/sqllogictest/file?name=test/select1.test&ci=tip) for reference)
Currently this is not possible since the `CREATE TABLE` expression is not supported.
