Description

Calls to SUBSTR function with arguments of not compatible types does not cause validation errors in some cases:

# 1
SELECT SUBSTR(100, 1)}

IgniteProject(EXPR$0=[SUBSTR(_UTF-8'100':VARCHAR CHARACTER SET "UTF-8", 1)]), id = 20
  IgniteValues(tuples=[[{ 0 }]]), id = 18

# 2
SELECT SUBSTR('123456789', '1')}

IgniteProject(EXPR$0=[SUBSTR(_UTF-8'123456789', 1:BIGINT)]), id = 41
  IgniteValues(tuples=[[{ 0 }]]), id = 39
{code}

# 3
SELECT SUBSTR('0000'::UUID, 1)}

IgniteProject(EXPR$0=[SUBSTR(CAST(_UTF-8'0000'):UUID NOT NULL, 1)]), id = 83
  IgniteValues(tuples=[[{ 0 }]]), id = 81

# 4
SELECT SUBSTR('123456789', ?, 1)

Dynamic parameters: [00000000-0000-0000-0000-000000000000 <java.util.UUID>]

IgniteProject(EXPR$0=[SUBSTR(_UTF-8'123456789', ?0, 1)]), id = 104
  IgniteValues(tuples=[[{ 0 }]]), id = 102
