------------------------------------
Summary: ARRAY_REPEAT with a string argument causes a compiler
crash
Key: CALCITE-6347
URL: https://issues.apache.org/jira/browse/CALCITE-6347
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.36.0
Reporter: Mihai Budiu
The following SqlOperatorTest:
{code:java}
f.checkScalar("array_repeat('1', 2)", "['1', '1']",
"CHAR(1) NOT NULL ARRAY NOT NULL");
{code}
causes a compiler error:
{code}
Error while compiling generated Java code:
...
static final String $L4J$C$org_apache_calcite_runtime_SqlFunctions_repeat_1_2_
= org.apache.calcite.runtime.SqlFunctions.repeat("1", 2);
...

at
org.apache.calcite.prepare.CalcitePrepareImpl.prepare2_(CalcitePrepareImpl.java:666)
{code}
This happens because the "repeat" function in SqlFunctions is overloaded to
implement both ARRAY_REPEAT and REPEAT.
